[Help-gsl] gsl_rng_alloc causing crash

[mike cantor]

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,

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
