--- Comment #2 from Tamar Christina <tnfchris at gcc dot gnu.org> ---
The latest master seems to not trigger the problematic specializations.

Instead check out commit d7ddbf366197605642f725cce6165dfb179a114e 

and then a normal

CFLAGS="-O3 -w -save-temps" ./configure
make
make check

should show the issues. For me using an x86_64 build of trunk I get

=================================================================
api/test_dump.c
=================================================================
Segmentation fault (core dumped)

=================================================================
api/test_dump_callback.c
=================================================================
test_dump_callback.c:run_tests:44: json_dumps failed

=================================================================
api/test_object.c
=================================================================
Segmentation fault (core dumped)

and the dump.s file produced shows the error.
