            Bug ID: 63866
           Summary: ICE in C++ printer with -fdump-ipa
           Product: gcc
           Version: 5.0
            Status: UNCONFIRMED

Likely TYPE_NAME/TYPE_STUB_DECL aren't set properly for __ubsan_*_data.

int main () { int i = __INT_MAX__; i++; asm ("" : "+g" (i)); }

‘decl common’ structure, have ‘identifier_node’ in dump_aggr_type, at

URL: https://gcc.gnu.org/viewcvs?rev=217718&root=gcc&view=rev
Log:
    PR sanitizer/63866
    * asan.c (asan_global_struct): Create a TYPE_DECL for "__asan_global",
    put it into TYPE_NAME and TYPE_STUB_DECL.
    * ubsan.c (ubsan_type_descriptor_type): New variable.
    Function renamed to ...
    (ubsan_get_type_descriptor_type): ... this.  Cache
    return value in ubsan_type_descriptor_type variable.
    Create a TYPE_DECL for "__ubsan_type_descriptor", put it into
    TYPE_NAME and TYPE_STUB_DECL.
    (ubsan_get_source_location_type): Create a TYPE_DECL for
    "__ubsan_source_location", put it into TYPE_NAME and TYPE_STUB_DECL.
    (ubsan_type_descriptor, ubsan_create_data): Call
    ubsan_get_type_descriptor_type instead of ubsan_type_descriptor_type.
    Create a TYPE_DECL for name, put it into TYPE_NAME and TYPE_STUB_DECL.

    * c-c++-common/ubsan/pr63866.c: New test.
