Well, not intentionally! I'm just calling "deallocate" in a purely
Fortran program. No C++ around anywhere.

If I compile with --with-memory-manager=none the program runs to
completion with no problems.

I've tried, but I'm not convinced valgrind understands Fortran 90. I
certainly don't understand valgrind... It spat out a lot of
information, but I don't think any of it was especially relevant to
this issue.
