[Bug fortran/41717] New: [4.5.0 regression] internal compiler error: in expand_debug_expr

["reuter at physik dot uni-freiburg dot de" <gcc-bugzilla at gcc dot gnu dot org>]

When compiling the attached code with the following flags:
gfortran -g -O2 -c state_matrices.f90
(actually the default from libtool for the debug mode), this triggers the
following internal compiler error:
