F90 programs are not currently instrumented on BG/Q platforms

The source of the problem is a lack of MPI profiling symbols available in the default MPICH build provided by IBM.

Problem is not present in recent custom MPI builds on the same platform.

Need to investigate if any workarounds (such as explicitly instrumenting Fortran-specific symbols) are viable.

Should also check if this problem is still manifested in Intel MPI releases as well.
