You have stumbled into one of the darkest corners of gfortran.
Our implementation of modules is almost completely undocumented
and the code leaves much to desire.  I spent a week or so
looking at a problem with "USE, only : a => z, b => z" where
the "b => z" causes an ICE because the "a => z" removes z from
the symbols in the module.  I also tried to understand the 
problem with EQUIVALENCE in modules.  I gave up. ;-(
