Asan help request

Could somebody with asan installed help me figure out which
commit on the smoke-me/padconst branch is causing asan to
get upset? I don't understand the output in the log at
<http://m-l.org/~perl/smoke/perl/linux/smoke-me_clang_sanitize=address/Father Chrysostomos/log9f8bc17bee719380806fbe448f675e416a5d9b57.log.gz>.
