_______________________________________________________
Details:
The following gives a segfault:
#include <stdio.h>
#include <math.h>
#include <gsl/gsl_errno.h>
#include <gsl/gsl_sf_hyperg.h>
int main (void)
{
gsl_sf_result result;
gsl_set_error_handler_off();
int status = gsl_sf_hyperg_1F1_e(1.0,NAN,-1.0, &result);
if (status == GSL_SUCCESS) {
printf ("success: %.18e\n", result.val);
} else {
printf ("failure");
}
return 0;
}
>From my understanding of the error handling, the _e functions should return an
invalid error code instead of crashing in such cases.
