this is the crashing context:

the crash is at 1E7B, the far call (which is your call gate).

it is easy to see that GCC expects that register ESP isn't changed in inline assembly, which is not true if PUSHAD is done.

Fortunately, one can see as well that GCC saves registers EBX, ESI and EDI on its own, so there is no need for the PUSHAD.
