Comment (by kencu):

 Somewhat strange. Things go smoothly until the build starts to build
 {{{compiler-rt}}} with the newly-minted clang, and then that crashes, as
 per your crashlogs.

 I have seen that before, when llvm was built with a too-old clang version,
 but on your system, llvm-3.7 should have been built with clang-3.4, and
 that does built it correctly.

 The buildbot last built clang-3.7 correctly on 10.7 in January
 <https://build.macports.org/builders/ports-10.7_x86_64-builder/builds/15670>
 but there have been a few (minor, I thought) changes to clang-3.7 since
 then.

 I'll try on my 10.7 system again to see.

 Do you have a version of clang-3.7 installed at this time, that you are
 trying to update? Does it work? Or crash?
