--- Comment #2 from noamb <noamb at bollweevil dot gdbg.org> ---
From Dominique d'Humieres
> Duplicate of pr71412?
This one is probably related, but does not actually involve calling a C
routine. Also, that previous bug has different dependence on -O level (works
with -O0, fails with -O1, -O2, -O3, at least on OS X gfortran 4.9.3 from
macports)
I do not observe correct behavior with the options that the previous comment
list s as being turned on by -O1 (this is on OS X 10.10, macports gfortran
4.9.3):
[bernstei@rhodium tmp]$ gfortran -v
Using built-in specs.
