Bug ID: 38610 Summary: winedbg fails to start in some cases when an application crashes Product: Wine Version: 1.7.18 Hardware: x86 OS: Linux Status: NEW Keywords: regression Severity: normal Priority: P2 Component: shell32 Assignee: wine-bugs@winehq.org Reporter: gyebro69@gmail.com CC: madewokherd@gmail.com Regression SHA1: 2005be6dc92c0943ede01525cecad88f8e83c9c7 Distribution: ---
I noticed this problem in a few cases: when certain application/game crashes the last line written in the terminal is something like this:
wine: Unhandled page fault on write access to 0x7e09e28c at address 0x7b853a3f (thread 002a), starting debugger...
then winedbg simply quits without generating the backtrace/module list.
Reverting the following commit fixes the issue:
2005be6dc92c0943ede01525cecad88f8e83c9c7 is the first bad commit commit 2005be6dc92c0943ede01525cecad88f8e83c9c7 Author: Vincent Povirk vincent@codeweavers.com Date: Wed Apr 16 15:50:37 2014 -0500
shell32: Use CREATE_NEW_CONSOLE when SEE_MASK_NOCONSOLE is omitted.
After reverting the commit winedbg is starting as expected: http://pastebin.com/4GRTtLaR (that's a game installer that crashes)
Tested in wine-1.7.43-25-g0d91274 Fedora 21 x86

I have yet to find such an app which is publicly available.

Do you not get a crash dialog?
I completely forgot about the crash dialog because I always disable it in the first place after creating a wineprefix. So the problem occurs when the crash dialog is *disabled*. Backtrace is shown properly when the crash dialog is enabled.

--- Comment #5 from Vincent Povirk madewokherd@gmail.com --- I'm guessing it's just not getting to your terminal because winedbg prints to the win32 standard output, which was (probably correctly) detached by ShellExecute starting with that commit. There's no reason to expect the stdout stream winedbg inherits from random crashing processes to always be useful, maybe it's a bug that the backtraces go there rather than the Unix stdout.

--- Comment #6 from Béla Gyebrószki gyebro69@gmail.com --- Rhino 4.0 installer from bug #17823 crashes at the end of installation. With disabled crash dialog terminal output ends with:
wine: Unhandled exception 0xe06d7363 in thread 41 at address 0x7b8397c4 (thread 0041), starting debugger... fixme:shell:SHChangeNotify ignoring unsupported flags: 2001
If I revert your patch then the backtrace is written too.

--- Comment #8 from Vincent Povirk madewokherd@gmail.com --- I think it's reasonable to expect that if you change the default and turn off the crash dialog, you may not be able to find a backtrace. It was never a guarantee that you would, it's just coincidence that you used to get it and now you don't.
If you don't want the crash dialog, and you do want the backtrace, you may have to put in more effort like manually attaching winedbg or starting the process through winedbg.
