Interesting - this might be related to my pthread-stubs patches.

Vinson, please provide a complete configure line alongside the summary and more information about the platform/setup.

fe56c745b8cb562445b318bacbb4267f07e43584 is the first bad commit
commit fe56c745b8cb562445b318bacbb4267f07e43584

    Convert sed(1) syntax to be compatible with FreeBSD and OpenBSD
    
    BSD regex library doesn't support extended RE escapes (e.g. \+) and
    shorthand character classes (e.g. \s, \S) and SVR4-style word
    delimiters[1] (on DragonFly and NetBSD). Both GNU and BSD sed support
    -E and -r to enable extended RE but OS X still lacks -r.

What does LLVM_CXXFLAGS contain in config.log before and after that commit?
