some registry keys in regedit causes regedit to crash.
Err, this is because GCC is extremly stupid. It loads a stack structure
into ebx, and then the callback code becomes jmp(%ebx). The problem is that it restores protected registers
before doing the
jmp, so ebx is reset to it's value before the function is called...
I guess this needs to be made __volatile,
It's just "volatile" (no leading underscores since it's a C keyword, not
a
language extension).
