I'm guessing it has to do with the compiler's attempts to optimize the generated code.
This said, I have actually not passed any optimization flags when compiling wine git with clang 3.3 (neither on OS X, nor on Linux.) I figured configure/the Makefiles would default to -O2. Instead, there's no optimization taking place (as I can see in the current compilation output of both apple gcc 4.2 and vanilla clang 3.2.)
Thanks for catching that, I'll take a look at what the Linux box does and will also play around with optimization levels.
