This is with the Fortran bindings to the GNU Scientific Library,
http://www.lrz-muenchen.de/services/software/mathematik/gsl/fortran/
Compiling works OK, but the test suite shows a couple of failures with
gfortran:
Running montecarlo.exe:
FAIL: fgsl_monte_monte_vegas_getparams
FAIL: 1 of 21 tests failed
fgsl_monte_monte_vegas_getparams: aborting Execution
Running multimin.exe:
FAIL: fgsl_multimin_fdfminimizer_iterate
FAIL: 1 of 12 tests failed
Running error test:
OK: All 6 tests passed
FAIL: fgsl_interp_alloc:nofail
FAIL: 1 of 1 tests failed
The "multimin.exe" test might be a bug in the test suite as g95, ifort and
gfortran show the same error. (For g95 it is the only error, the ifort has
additionally for array.exe/poly.exe a segfault.)

------- Comment #1 from burnus at gcc dot gnu dot org 2009-09-07 10:29 -------
With GCC 4.4 one has only the "montecarlo.exe" and "multimin.exe" error, but
not the "error.x" error.

The "error.x" failure is presumably due to PR 41297.

The montecarlo.exe issue is PR 41298.

------- Comment #4 from burnus at gcc dot gnu dot org 2009-09-07 16:56 -------
Regarding multimin.exe:
The second call to unit_assert_equal_within fails. For the first, the expected
value is 30 and it succeeds.
For the second one, one does 13 loops with fgsl_multimin_fdfminimizer_iterate
with status == 0 and a minimum of mmin_fmin of 3.5e-317 (unchanged). After the
loop there is a check whether this number matches (within 1e-5) the number 30
which fails:
fgsl_multimin_fdfminimizer_iterate 3.000000000000000000D+01
3.511692129834245077-317 1.0D-05
I currently assume that it is a test bug, FGSL or GSL bug.

I just compiled GSL 1.13, FGSL 0.9.2 and run "make test" without any failure.
Thus: Close as FIXED.
Note: I have a patch for PR 41298 applied,
cf. http://gcc.gnu.org/ml/fortran/2010-01/msg00047.html
