--- Comment #22 from Ville Voutilainen <ville.voutilainen at gmail dot com> --- Created attachment 33664 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=33664&action=edit Preprocessed source for is_trivially_copy_constructible tests This test fails the static_assert for TType (which is a trivial type), PODType and DelDef, and it would be expected that all those static_asserts succeed. Then, the compiler segfaults, trace: [ville@localhost is_trivially_copy_constructible]$ g++ -v -save-temps --std=c++11 -I ../../util/ -c value.cc Using built-in specs.
