[llvm-dev] type traits bug in clang 4.0.0?
Dear all, I found this strange behavior, when inspecting some legacy build that did not compile after an upgrade of several libraries and clang: https://stackoverflow.com/questions/44846377/what-is-the-reason-behind-instable-type-traits I got no conclusive answer, but a comment that indicates that this might indeed be a bug in clang. Since I am neither a C++ expert nor familiar with clang, I would very much appreciate if some expert could: 1. verify that this is indeed a bug 2. help me to formulate this as a constructive report (i.e. what is actually going wrong here w.r.t. the C++ standard) and/or further reduce the test case thanks a lot, Christoph -------------- next part -------------- An HTML attachment was scrubbed...

I tried the posted code on SO and it also fails to compile on clang 5.0svn.
