You're probably running out of stack space, as per the faq on the web
page and noted in the debugging section of the manual.
mpz_get_str isn't normally a blindingly fast operation, maybe we
should make it use malloc instead.
mpz_ui_pow_ui in your example also uses quite a bit of stack space in
fact.
