Subject:   Weird breakage on 14.4-p6 to 14.4-p8 upgrade

On Monday I upgraded one of my servers from 14.4-p6 to 14.4-p8, and
after the reboot, yaf (net-mgmt/yaf) immediately started crashing with
SIGSEGV about once per CPU-minute.  The package hasn't changed
(although I did force-reinstall it just to make sure there was no
corruption in the executable).  I was able to attach to a running in
lldb before it crashed, and the crash appears to be a null-pointer
dereference, but obviously *this wasn't happening before*, and I don't
see anything in UPDATING for -p7 or -p8 that looks like it could be
remotely relevant.

There's no core dump; the kernel logs:

pid 4650 (yaf), jid 0, uid 65534: exited on signal 11 (no core dump - bad address)

Anyone have any clues?
