Multiple [NSWindow(NSSheets) _documentWindow] in crash stack

General
1

Hi there,

I’ve got someone who’s reporting a hard crash in our application. The error report which is given says that thread 0 crashed, and then lists this:
com.apple.AppKit 0x978fe8b5 -[NSWindow(NSSheets) _documentWindow] + 91
where is 0 thru 511. So, 512 lines the same.

Can anyone tell me what I might be doing wrong here?

Thanks!

I should point out that the exception type and code is this:
Exception Type: EXC_BAD_ACCESS (SIGSEGV)
Exception Codes: KERN_PROTECTION_FAILURE at 0x00000000bf7ffffc
There’s lots of stuff on Google about that code, but nothing really helpful that I’ve found…

Without a full crash log (which is far too big for the forums) its hard to tell
A bug report with the attached log would be useful

Thanks, Norman!

Unfortunately stack overflows like this don’t produce very useful crash logs as the source of the problem is much further down the stack than the 512 frames that CrashReporter is willing to write out. What’s necessary is a way to reproduce the problem (and a bug report).

Hi -
Sadly it’s in a built app, and only reproducible on someone else’s machine which I don’t have debug access to.
Is there anything I can do on that machine with a special build, or something similar, which would help?
Thanks,
Hamish

There is already a Feedback issue - don’t remember the number, can’t look it up at the moment. As usual it was closed because it wasn’t reproducable. I get one of these crashes every few weeks.
