--- Comment #1 from Rainer Orth <ro at gcc dot gnu.org> ---
I just noticed I messed up: this ICE happens only for a single testcase:
FAIL: gm2/iso/run/pass/testgeneric.mod compilation, {additional_flags= -Os }
(internal compiler error: in output_constructor_regular_field, at
varasm.cc:5515)
for both 32 and 64-bit.
