--- Comment #2 from Norgg <gcc at norgg dot org> ---
It seems the -fmerge-all-constants isn't necessary to cause the segfault either
any more, although it was in an earlier larger test case.
Minimal command line to reproduce is now:
$ g++ const_crash.cpp -flto
const_crash.cpp:11:24: internal compiler error: Segmentation fault
template class foo<int>;
