--- Comment #2 from labath at google.com ---
Removing bin/llvm-ranlib does indeed make the problem go away (thanks for
that). However, I believe this only solves half of the problem. The first issue
I mentioned still exists: I do not think llvm-nm should crash when processing a
corrupted file, even if that file was produced by accident. If it's not
possible to recover from that situation then we should replace the call to
llvm_unreachable by exit() and an error message, but for example GNU nm just
prints a message about unrecognized format and then it continues to parse the
rest of the files in the archive (apparently correctly).

I will reopen this so that someone else has a chance to look at it.
