The segfault is due to the DECL_NAME call, which then fails the contains_struct_check and causes a segfault. According to 5a5e7deb5f93f04e027fd5baa1876370d6d6697f and 78fcec3fee63f10cfde06c252fc391e768c64b12, the correct fix would be to wrap the call in DECL_NAME, no? Yet that just causes the contains_struct_check to fail on the if DECL_NAME (TYPE_NAME (type)) call.
