Then please submit a patch in a PR.  I did the original config.h and I am
not a powerful CSH user, so I made best guesses.  FreeBSD survives

Maybe.  One that cares should email Christos to find out if it is a bug
or feature.  Those that experience the problem are the ones in the best
position to explain and get to the bottom of the issue.

Current and RELENG_4 do differ in the default malloc.conf settings.
Current uses "ADJ<".  Can you try those settings on RELENG_4 and see if
it changes anything?
