[Bug 24068] New: Crash in dbghelp on 64-bit (WoW)
http://bugs.winehq.org/show_bug.cgi?id=24068 Summary: Crash in dbghelp on 64-bit (WoW) Product: Wine Version: 1.3.1 Platform: x86-64 OS/Version: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: dbghelp AssignedTo: wine-bugs(a)winehq.org ReportedBy: adys.wh(a)gmail.com See attached backtrace. Note: I cannot repro the crash that got me there in the first place, so I won't be able to give further logs. However, I was hinted on IRC the backtrace could contain enough data to figure the bug out. [06:34:13] <KittyCat> looks like it's unwinding the stack, so it might just be a thrown exception. can't tell if it's unhandled or not.. [06:35:33] <@Thunderbird_> dwarf2_virtual_unwind does nothing with context it just passes it through at the end of the call to this helper function (perhaps it should have checked context before? I don't know the code) [06:40:56] <KittyCat> hmm. this doesn't look like it should even compile.. [06:42:08] <KittyCat> oh, wait. okay [06:43:08] <KittyCat> it's dereferenced so it can be copied to a temp and restored later [06:43:42] <KittyCat> and some of the switch cases may do something with it [06:44:44] <KittyCat> might have to ask Eric Pouech what's supposed to happen if it's given a NULL context pointer [06:46:11] <KittyCat> or AJ [06:55:56] <KittyCat> looks like that code was added in commit 036392c5d131d73e84ad0ed52a796b2cb9c1139d, on March 27th [07:02:13] <KittyCat> it seems, before that commit it'd have fallen back to a default_unwind() function, which would also take and use the context (unless sw_read_mem failed) [07:06:03] <KittyCat> it looks like it's calling StackWalk explicitly [07:09:08] <KittyCat> from the looks of it, wow is calling StackWalk with a NULL context. msdn doesn't seem to have StackWalk, but according to StackWalk64: [07:09:14] <KittyCat> "This parameter is required only when the MachineType parameter is not IMAGE_FILE_MACHINE_I386. However, it is recommended that this parameter contain a valid context record." [07:09:30] <KittyCat> and MachineType is being set to IMAGE_FILE_MACHINE_I386 [07:20:46] <KittyCat> from glancing at related commits, it doesn't look like StackWalk ever properly handled a NULL context parameter [07:21:46] <KittyCat> though it wasn't until about March 24th that it was actually used -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

I was able to reproduce this with the WoW Cataclysm Beta client. You can reproduce this by attempting to view the WoW Burning Crusade Cinematic sequence from the main menu. Click on the Cinematics menu on the right hand side of the login screen and it will give you an option of which Cinematic scene to watch. On windows, clicking on any of the cinematic options causes the login screen to reload, on wine it causes the dbghelp crash.
