Thank you for all the input.

Mostly, you will get a SIGILL if you take out more than you put in,
because the return adress on the stack will no longer be ok.
I don't really like va_args ..

I made the change and recompiled everything. The new crash looks like this:

Program received signal SIGILL, Illegal instruction.
g_type_check_is_value_type (type=2305843009213693976) at gtype.c:2731
2731    {
(gdb) where
#0  g_type_check_is_value_type (type=2305843009213693976) at gtype.c:2731
#1  0x20000000009b2ac0 in g_type_check_is_value_type (type=0) at gtype.c:2731

I think I'll have to dig deeper into this, because the fix does not
seem to be absolute. Ah well, ...

I don't access to an alpha,  :( and I'd like my program to run on this
Itanium here :| .
