Weird-- I'm also on Yosemite.But anyway if you cannot repro, let's forget about this for now. I'm never too concerned about random clang_delta crashes, these might slow down reduction a bit, but they seldom change the final result -- in my experience the program construct that triggers the crash usually gets reduced away later on, and then clang_delta succeeds the next time it runs.

I tried the pre-built version from llvm.org and a debug version built locally on my machine. They worked fine. BTW, I looked through the valgrind output that you posted, but couldn't find any clue. It's quite strange. Eric, when you get a chance, can you try it out on your Mac? Thanks. - Yang
