Hi,
the following backtrace is from a crash that happened when building
www/chromium with clang. The chromium port builds a binary protoc which
crashes when built with clang.
Program received signal SIGSEGV, Segmentation fault.

...
So the question is if this is a protoc or a clang or a libstdc++ bug.
