Hi,
The following program crashes for me on MS Windows 7, gmp-6.1.2, when the
line "gmp_randseed_ui(b, 123456);" is executed.
I built gmp in the MSYS2 shell using gcc version 5.3.0
(x86_64-posix-sjlj-rev0, Built by MinGW-W64 project).
Configure command was:
./configure
CC="gcc -D__USE_MINGW_ANSI_STDIO" --enable-static --disable-shared --enable-assembly
LDFLAGS=-LC:/_64/msys_530/1.0/local/lib
CPPFLAGS=-IC:/_64/msys_530/1.0/local/include --prefix=C:/_64/msys_530/1.0/local
/*********************/
#include <stdio.h>
#include <gmp.h>
int main(void) {
gmp_randstate_t a, b;
gmp_randinit_default(a);
/* gmp_randseed_ui(a, 123456); *//* same result with or without this line
*/
gmp_randinit_set(b, a);
/* printf("%s\n", gmp_version); *//* outputs 6.1.2 */
gmp_randseed_ui(b, 123456); /* crashes */
return 0;
}
/********************/
AFAICT this is a gmp bug, but I don't rule out the possibility that it's a
user bug.
If "a" is initialised with either gmp_randinit_lc_2exp() or
gmp_randinit_lc_2exp_size() there is no crash.
Cheers,
Rob
