    IE can't handle the softness of that hyphen!


  • BINNED


    Something else missing?


  • area_deu

    Maybe it actually needs line breaks. Fixed!


  • BINNED

    Indeed.

    It's also only when you scroll up to place it in view



  • Here's what I see on chrome. What did you expect to see? What do you see in IE now?

    A headache inducing border around the window?

    :trollface:



  • Humorously enough, IE10 also crashes, but putting it into IE9 Browser and Document modes and the topic is fine.

    Also opening it without the OP in view in IE10 normal was fine, but when I scrolled up to the OP I got:

    Hitting "Don't Allow" crashed the tab. Hitting "Allow" froze IE for a minute or so, then crashed the tab.


  • area_deu

    ... :wtf: is dw20.exe?!


  • SockDev

    Dr Watson; it's some sort of diagnostic and crash reporting tool MS package in Windows


  • SockDev

    what is......

    #HOW‽‽



  • @aliceif said:

    dw20.exe

    Then it already crashed, windows however is still trying to decide that and/or create a crashdump


  • area_deu

    Oh fuck me.
    Accidentally hit edit instead of reply



  • Does IE run tabs in their own processes? Could be how the parent process interprets Dr Watson's appearance.



  • @boomzilla said:

    Yes.

  • area_deu

    Doesn't help that the editor is initially empty when you select edit ...



  • @aliceif said:

    Oh fuck me.Accidentally hit edit instead of reply

    :rofl:

    I've done that before a few times.



  • I think it's more Discourse slowness, and not with editing, but with populating the editor in general.

    I've had points where hitting Edit gives me a blank post, but right now it's showing content fine when I click Edit. I've also had points where clicking "Quote Reply" gives me a blank editor for awhile too, which I attributed to server cooties.



  • That is...a very impressive level of fail on the part of IE. Is the topic that triggers this in a place visible to random browsing?



  • @tarunik said:

    Is the topic that triggers this

    You mean this very topic we're in right now?

    @tarunik said:

    in a place visible to random browsing

    No lock or key icon on the category, so yes, this topic can be viewed by the world.


  • area_deu

    Yes. If you scroll to the OP of this thread, your IE tab will crash.



  • Confirmed on IE 11.0.17 on W7 x64.

    More info: crash is a NULL pointer deref, apparently due to this being NULL in the call to CDXRenderTarget::FillGeometry() (it looks to be a COM interface implementation internal to mshtml.dll which makes it __stdcall instead of __thiscall). Backtrace:

  • I survived the hour long Uno hand

    IE 11.0.19, Win 8.1 x64

    EDIT :hanzo:



  • Anyone tried this with Edge?



  • @aliceif said:

    Oh fuck me.

    OK ...

    I mean no problem I was wondering what I posted that required a spoiler



  • @boomzilla said:

    Does IE run tabs in their own processes?

    Yes only the tdwtf tab crashed. SharePoint kept running.



  • Followup:

    CDispSurface::DrawCharactersWithFillAndStroke pushes a bunch of args on the stack, and then calls CDBindMethodsSimple::~CDBindMethodsSimple() {} (yes, it's a no-op dtor) right before calling CDXRenderTarget::FillGeometry().

    However, even though what looks like a valid this ptr from the caller's side is being pushed onto the stack right before the two calls -- it never makes it to the callee, who instead proceeds to read the word above it on the stack frame, which is a NULL from a local variable pushed by the caller, and die. This all smells of two subroutines which can't agree on parameter passing (either mismatched argument lists, or worse yet, a calling convention mismatch), but how could that sort of bug slip past the gates of Redmond? :wtf:

  • I know!



  • That's a strange use of shy; it's supposed to be used in words to indicate the location a hyphen should be inserted if a word break is needed at EOL.

    verylongveryverylong verylongveryverylong verylongveryverylong verylongveryverylong verylongveryv st­raig­ht

    verylongveryverylong verylongveryverylong verylongveryverylong verylongveryverylong verylongveryve st­raig­ht

    (Having some problems with baking. Finally got an example.)

    Notice that where it appeared, the hyphen was put between g and h or between t and r...both very odd places to hyphenate the single-syllable straight. Both words have indicated shy points: st-raig-ht.

    It may be the unusual solitary use that's causing it.

    It might be awful and semantically meaningless, but it's still a legal sequence in HTML. It shouldn't make the browser's renderer keel over!



  • @dkf said:

    Oh, sorry, didn't mean to imply otherwise. I was just discussing thoughts on why they might have overlooked such an egregious fail.

    Browser must not fail even when input violates every sensible rule.

    We had a discussion about another aspect of that--what happened when you nest tags to more than 150 levels or something like that. While I argued that ignoring levels was acceptable, my reasoning was because it was better to ignore levels than to fail outright.

    Otherwise you get user panics, "Oh noes! I've been hacked! My browser failed!"


  • Discourse touched me in a no-no place

    @CoyneTheDup said:

    There's fail and then there's fail. Crashing comes into the latter category, especially when we're talking a relatively simple combination of HTML, an (unusual) entity, and CSS. Just not drawing it at all (or, conversely, always drawing it) would be more in the former category.

    That's better attributed to quoting requiring a server round-trip. I'm pretty sure the UI makes a ton of unnecessary round-trips to the server.


    Good work on finding an IE bug! Is it reported yet?

    Oh yeah, Microsoft doesn't have a public bug tracker.



  • @riking said:

    quoting requiring a server round-trip

    Don't we already have both the raw and the cooked ? Otherwise the "view raw" wouldn't work, would it ?



  • No, that round-trips.



  • ah, i see. It seems to do so way faster than the edit text appears tho.



  • Probably because it's fetching the whole post.

    And the round trip sucks because of cooties.
