I might be guessing wildly since I don't know that much about PE, but this is
what more I've found:
It crashes loading the dll in __pei386_runtime_relocator at address 65ec12a8

Thanks. Is there anything that can be done in the code to say that is not a
leaf function, or at least to tell gcc that a call is being made inside the
inline asm?

That won't work in this case. If I subtract anything from rsp inside the inline
asm, the local variable relative to f will no longer be valid. Notice where gcc
put it:
21: ff 54 24 f8

Still reproducible with 4.5.0. For example:
../gcc-4.5.0/configure --target=i686-pc-mingw32 --enable-languages=c
--program-prefix=i686-pc-mingw32- --program-suffix=-4.5.0
--enable-version-specific-runtime-libs
