Fwd: Re: [interprocess][move] enum template argument fails to be a valid base class
i think I spoke too fast, is_enum needs compiler intrinsics according >to boost documentation, so maybe this approach is not very useful...
Forget it. I was talking about is_union instead. God, the lack of coffee is killing me ;-) Best, Ion

Hrr, I have added you suggestion and in addition a specialization for is_enum to emulate the compiler behavior namespace boost { template <> class is_enum<Test::Types> : public mpl::false_ {}; } But this doesn't avoids the instantation of rv<Test::Types>. Why do you say that the bug is not in Boost.Move? Am I missing something in the protocol Boost.Move imposes? Best, Vicente

Why? And you say "False", so evidently, the commented trait will try to instantiatie rv. And the bad part is that is_enum requires instantiation, which breaks the possibility of recursive containers. And I don't want that to happen. Is there any possibility to detect an enum without instantiating the class? Best, Ion

Sorry fot the mistake. Unfortunately after changing to true_ there is no improvement. Best, Vicente

Ok, so I will need a bit more time to solve this issue, but I'm putting my effort on a new Boost.Move version now. I'll fix it ASAP. Best, Ion
