[Llvm-bgq-discuss] linker errors with llvm/current/bin/bgclang++

[Geoffrey Irving]

Cool, that gets me through linking and unit tests in debug mode and
optimized with -O2.  However, I get an illegal instruction in some
static initialization code if I use -O3.  I'll see how easy it is to
reduce my test case.

In any case, progress!

Thanks,
Geoffrey
