va_start? I don't see what's wrong there.

The code hasn't changed significantly since 2002-02-14 (1.0.8). That
change was the addition of the __attribute__ for gcc warnings.

That's the first call of DBG, I guess (from dll). ap is uninitialized,
but thats ok. msg points to the correct string.
As DBG is used in every backend and seems to work everywhere else I
would suspect a compiler bug.
Or, it's a memory corruption that happens somewhere before in the code
and the crash at this place is only a symptom. However, we are nearly
on top of the backend code. Maybe something in DBG_INIT?
Other opinions?
Bye,
Henning
