--- Comment #10 from Wesley J. Landaker <wjl at icecavern dot net> --- Created attachment 32248 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32248&action=edit uffff.c++ -- program that shows this problem, and bug #60397's problem I opened new bug #60397 that is a similar issue, but not the same problem. I've attached a new program that more simply shows the problem just using static_assert.
