I have to admit that I have never used the -J option myself, but the
documentation at
http://gcc.gnu.org/onlinedocs/gcc-4.7.0/gfortran/Directory-Options.html seems
to suggest that using "-Jdir" sort of implies "-Idir" (in the sense that this
directory is searched for .mod files).
Is there a particular reason that you use both of them? The problem may indeed
be due to the two interfering (which of course would be a bug). What happens if
you use neither -I nor -J?
In any case it would be helpful to have some sort of test case (it doesn't
necessarily need to be extremely reduced, but the smaller the better, of
course).
