Ok, revised version of the patch from comment 9, which fixes the runtime
failure on internal_pack_10.f90:

Note: This still shows scan-tree-dump failures on assumed_type_2.f90, but now
only 2 of them at -O0 (instead of 4):
FAIL: gfortran.dg/assumed_type_2.f90 -O0 scan-tree-dump-times original
"sub_array_assumed \\(D" 2
FAIL: gfortran.dg/assumed_type_2.f90 -O0 scan-tree-dump-times original

Will do another full regtest ...
