gmp-4.1.2 assertion failure

[Jason]

on linux athlon gcc-3.2.3
./configure --enable-assert --disable-shared
make
gcc -Wall -W jay1.c .libs/libgmp.a
./a.out

we get

n_pow_ui.c:468: GNU MP assertion failed: 2*(rsize) <= (talloc)

note need a lot of mem for this not to segfault

the "cause" is integer overflow at line 359 in n_pow_ui.c

ralloc = (bsize*GMP_NUMB_BITS - cnt + GMP_NAIL_BITS) * e / GMP_NUMB_BITS + 5;

as you can guess this is the bug I was really looking for

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#define WANT_ASSERT 1
#include "gmp.h"


int	main(int argc,char *argv[])
{mpz_t y,z;

mpz_init(y);
mpz_init(z);

mpz_set_ui(y,120);
mpz_mul_2exp(y,y,11);
mpz_add_ui(y,y,1);

mpz_pow_ui(z,y,300000000);


return 0;}
