[Help-gsl] gsl_rng_alloc causing crash |

Hi,
I am using gsl_rng_alloc in a C-coded python extension on windows XP (gsl
ver 1.6). The extension compiles and links fine but any call to
gsl_rng_alloc causes a fatal error. For instance, the example code the gsl
documentation (plus a few inserted printfs)
gsl_rng * r;
const gsl_rng_type * T;
gsl_rng_env_setup();
T = gsl_rng_default;
printf("about to initialize\n");
r = gsl_rng_alloc (T);
printf("initialized\n");
crashes having displayed "about to initialize" but before displaying
"initialized." I have tried a number of things, including (1) writing it
with and without the rng_env_setup() call (2) using different rngs (e.g.
gsl_rng_mt19937), (3) setting windows environment variables for
GSL_RNG_TYPE and GSL_RNG_SEED and using the corresponding type in the call
to gsl_rng_alloc. In all cases, the program crashes at the alloc call.
Any suggestions???
Thanks,
-mike
p.s. One additional piece of information: if I use
printf ("seed = %lu\n", gsl_rng_default_seed);
The seed printed is not what is set in the ENV var GSL_RNG_SEED
