Failing pFUnit framework version from http://sourceforge.net/projects/pfunit/
When trying to compile the Fortran unit test framework pFUnit with gfortran
5.1.0 I obtain an internal compiler error - it just works fine with gfortran
4.9.2.
Steps to reproduce in a Linux shell:
Unpack the attached version of pFUnit (or checkout rev. efa55c3c of
http://git.code.sf.net/p/pfunit/code)
> mkdir build_gcc5.1.0 && cd build_gcc5.1.0
> cmake ..
> make
