[Bug fortran/33530] New: Building fortran fails with ICE on target=x86_64-pc-mingw32

["nightstrike at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

When running the following:

../gcc/configure
  --target=x86_64-pc-mingw32
  --prefix=/tmp/rt64/scripts/buildsystem/root
  --with-sysroot=/tmp/rt64/scripts/buildsystem/root
  --disable-nls
  --enable-languages=fortran

and

make > /dev/null


I receive the following output (tail only):
