has_new_operator.hpp build failure

[Aamani kalepi]

Hi

I am trying to upgrade the version of boost from 1.42 to 1.55 in our product. After replacing with new boost source,i tried compiling the product and it throws below errors :

boost/type_traits/has_new_operator.hpp(132) : see reference to class template instantiation boost::detail::has_new_operator_impl<T>' being compiled

Could you please help me in resolving the bugs

I suspect you have "new" defined as a macro.

This fix: ​https://github.com/boostorg/type_traits/commit/954cdb5e46cddfb56dc90717d4a2fbd3de7f6ed7 should fix the issue and is present in Boost-1.56.

Please reopen if this is not the case.
