I forwarded the email to Jakub Jelinek, who implemented OpenMP in GCC,
and he agrees that this is seemingly a GCC bug and stated: "I'll handle
it once I get to it."

To track it, I filled the bug at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33904

This is also the suggested work around.

Well, independent whether the code is modifiable or not, gfortran should
compile any standard-compliant code.

Thanks for reporting the bug.
