Comment (by cooljeanius):

 Building with trace mode on allows the build to succeed. Some trace mode
 output that might be relevant:

 `readlink /opt/local/bin/g++` says it points to
 `/opt/local/bin/g++-mp-10`, so, I guess since clang is what's crashing, it
 must be because gcc is configured to use clang's assembler or linker or
 something?
