[Llvm-bgq-discuss] [maint at libelemental.org] Elemental build issues using bgclang on ALCF Vesta

[Jack Poulson]

Hi Sayan,

I have re-enabled the function by avoiding attempts to use non-static
member variables in compile-time expressions:

https://github.com/elemental/Elemental/commit/d74f61e8b4ec366cecc2510de8de5ff096a77c65

I can again locally build Elemental with Clang-3.5-1ubuntu1 (trunk).
