Here's what happens:

It's the function "glue", which is static inline, but still uses ebp.  Huh?
We are compiling -fomit-frame-pointer...?

The function spills eax, ecx and edx, takes two register arguments and two
memory location arguments.  Apparently, gcc 3.4 wants to put the memory
locations into registers as well...?
