Hi,
I have received a few cases like the trace below - it always happens in OSX
10.10 and runModalForWindow and crashes in CFStringDeallocate. Any ideas
what that could be? I have tested 4 computers, with like 6 different OSX
versions, always works here, yet there are machines where this happens
apparently, somewhere out there :). Moreover all the Cocoa calls here are
actually just wrapped in our crossplatform library, and there's not much
going on, that makes this especially surprising. NSStrings, which are
probably the issue here are always created from our MString like this:
const unichar *utf16 = (const unichar *)s.GetUTF16();
return [NSString stringWithCharacters: utf16 length: s.GetLength()];
The crash log excerpt:
