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

[Geoffrey Irving]

A reduced test case crashing bug is attached.  Usage:

    vesta:core% /home/projects/llvm/current/bin/bgclang++ -o bad -O2
bad.cpp && ./bad
    vesta:core% /home/projects/llvm/current/bin/bgclang++ -o bad -O3
bad.cpp && ./bad
    Illegal instruction (core dumped)
