Update of bug #25413 (project gsl):

                  Status:                    None => Need Info              


Follow-up Comment #2:

Thanks for the link.  I don't believe the test failure should be ignored or
worked around with -ffloat-store as the relative size of the error is huge

This suggests that there is a more serious underlying problem with extended
precision registers that is specific to Mingw as it doesn't with the same
versions of Gcc on GNU/Linux or other operating systems.

I'd suggest that you rerun the test with tracing for the vegas method by
adding s->verbose=1 before the call to vegas and see where the error is

#define MONTE_INTEGRATE(f,xl,xu,dim,calls,r,s,res,err) { s->verbose=1;
gsl_monte_vegas_integrate(f,xl,xu,dim,calls,r,s,res,err) ;  }
