Rather than giving a true-false answer, it fails to compile.

My suspicion is that GCC-4.6 is too old to give a decent answer in these cases, but I'll investigate.

comment:2 by akrzemi1, 7 years ago

I mean, it is fine, if it just returns false in GCC 4.6.

This should be fixed in ​https://github.com/boostorg/type_traits/commit/bc8a92c7b6ff76fa42d23f49f60d743f95d15798.

The change causes some runtime failures, but in the "safe" direction - not spotting things which are noexcept.
