Crash during elog.c...

My client (same one with the slru.c issue) has had 3 of these in the
past day...

The backtrace:
Program terminated with signal 11, Segmentation fault.

maxlen = 256, cursor = 0}

Asserts are on, but for performance reasons the memory checking stuff is
commented out.

The good news is there's been no slru.c asserts...
