I am having an issue with PCSX-R (http://pcsxr.codeplex.com), mainly that the 32-bit build crashes with a call to misaligned_stack_error_ when fseek is called. Is there a way to fix it so that I don't have to use -mstackrealign? I can't debug using gdb when I use it.

Okay, I figured out what was causing the issue: Apparently the i386 dynarec core that PCSX-R uses is 4-byte alligned, but Mac OS X code needs to be 16-byte alligned under i386. If it isn't, it crashes when it gets to a libSystem call.
