I've done a clean, and thrown out the personal files in .xcodeproj.

What's the specific crash? Illegal instruction? Access violation?
EXC_BAD_ACCESS. r29 is 0x7fffdead.
I'm getting a slightly different stack today

If it's the former, is there any chance your stack could be
misaligned? The Mac OS X x86 ABI requires 16-byte-aligned stacks,
but assembly language written for other platforms may only be
written to preserve 4-byte alignment.
This is on PowerPC. There's no assembly in this application.
