Xcode “EXC_BAD_ACCESS” - my bug, OF bug, Xcode bug?

Hi folks,

Every now and again - like twice a month - I’ll get a non-reproducible error like this while running my OF app with the Xcode debugger:

Program received signal: “EXC_BAD_ACCESS”.
Xcode could not locate source file: sweep.c (line: 1026)
kill
quit

I don’t have any references to any “sweep.c” in my code, so I’m thinking maybe it’s a Xcode/GDB error… or maybe something in the libraries that OF uses. Anything I can do to further investigate this? Second time it happened, it was a different file, not sweep.c, but it was still a file that I don’t have in my code directly.

I’ve had this happen while using Xcode 3.2.2 and 3.2.3 on OS X 10.6.3, as well as 10.6.4 - all the while on OF v0.061 for iPhone.

Cheers for any advice.
