Thanks!  That's more than what I was asking for, by the way. :)

Hm, this seems odd --- wouldn't xrealloc call realloc (which calls malloc),
not calloc?

So I suppose output from "frame 2; disas; frame 3; disas" would still
be useful, or even better, I should just find time to spend on a
powerpc porterbox to analyze the core dump you sent.

Thanks again.
