Hi,
Thanks for the bug report. It would be good to get GSL working on this

Can you compare the values of FLT_MAX, FLT_MIN etc on your system with
the ones used in test.c. Try compiling with FLT_MAX, FLT_MIN in the
source code instead of the hardcoded values.

Yes, looks like a variation in rounding only.

This error is perhaps more serious, I have never seen it fail before
-- can you step through the appropriate part of the test program under
the debugger?
Thanks,

p.s. what compiler do you use?
