Xcode 3.2.3 - Debugger shows only _string.h

In certain locations in my application, if I place a breakpoint and go to that location the code window jumps m开发者_开发技巧e to _string.h (which is locked) to this function.

static __inline void *
__inline_memcpy_chk (void *__dest, const void *__src, size_t __len)

When I hit Step I am stuck, and all I see is _string.h. My code still executes and I see my NSLog().

A quick fix is to run in release mode, but in my project I have special code that happens in release. So this isn't really an option.

Does anyone know what is going on?

Thanks.

The problem appears to be caused by my project being a universal build. We created an iPhone version of the build and I can walk through the section of my code where I couldn't before. But then I have the issue of not being able to view my variables.

Oddly enough when I go back to the universal build I don't have the problem in my code, and I can debug normally. Not the greatest fix but at least I can work.
