re PR ipa/59947 (Segmentation fault with #pragma GCC optimize ("O2"), ICE in get_odr_type)
PR ipa/59947
* ipa-devirt.c (possible_polymorphic_call_targets): Fix
a comment typo and formatting issue. If odr_hash hasn't been
created, return vNULL and set *completep to false.
* g++.dg/opt/pr59947.C: New test.
