Clang 3.9.0 segfaults with variant/using-declaration #121

Closed springmeyer closed 7 years ago

springmeyer commented 8 years ago

This ticket is to document that mapbox::variant usage may trigger a segfault in the recent clang 3.9.0 release. There is unlikely anything we need to do in mapbox::variant, but I'd like to keep this open as a notice until the issue is resolved in clang.

Original mapnik usage of variant that uncovered the problem: https://github.com/mapnik/mapnik/issues/3507

Bug against clang is being discussed at https://llvm.org/bugs/show_bug.cgi?id=29087. Since this is a clang regression there appears to be nothing we need to do on our end. Closing.
