Comment (by howarth.at.macports@…):

 Just to be clear, this is considered a defect in both llvm.org and Apple
 clang so no hack will be forthcoming from the FSF gcc developers. Upstream
 lllvm.org needs to eliminate this regression in the improper setting of
 the CIE version in the absence of debug flags.
