this could easily be a machine independent buglet which only happens to
show up on alpha with a SIGFPE but could show up in subtle ways or not at
all on other systems (including alpha with -mieee). I looked a little,
but didn't see anything.

I've fixed most of them. The huge number generated by kaffe.def is
because the program counter ends up being a long int which is 64 bits on
alpha while the dprintf's between lines 53-60 of
kaffe/kaffevm/intrp/machine.c use %d for the format string. %d is an
integer which is 32 bits. On something like i386, sizeof(long) ==
sizeof(int) == 32 so there's no problem.
By changing to %ld, my warnings went away. You may want to also cast to a
long too. Ie, dprintf("pc=%ld", (long) pc).
in kaffe/kaffeh/support.c, these warnings may be a bit worse:
support.c:422: warning: cast to pointer from integer of different size
support.c:423: warning: cast to pointer from integer of different size
f->name = (void*)((u4)name_index);
u4 is a uint32 (32 bit integer). Then you're casting to a pointer which
is 64 bits. But then again name_index starts out as a u2 (16 bit
number?) so maybe you don't care about the top 48 bits...
support.c:504: warning: cast from pointer to integer of different size
support.c:505: warning: cast from pointer to integer of different size
name_index = (u2)(u4)(f->name);
same thing in reverse.
I'll attach patches after running another 'make check' with these format
