frequently (note that's out of 100, not 1000):

fluffy533% clang -v
Apple clang version 4.0 (tags/Apple/clang-421.0.60) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin12.1.0
Thread model: posix

Segmentation fault: 11

Segmentation fault: 11

Seems to be anywhere from 2-8 out of 100 here.

FYI,

NetBSD x86-64's fine w/ clang 3.1.  No failures over 1000 tests.
