He means RELENG_4_3 patch level 28, which is the most recent security
patch on that branch (approx 10 days ago).
There have been a few reports now (see also kern/35969) of crashes
that seem to correspond to the kernel zlib error-handling fix (it
is RELENG_4_3 patch 27). Maybe it has some problems? Actually, just
looking at the patch, I think it does...
The patch moves the position of one of the
ZFREE(z, s->sub.trees.blens);
lines to after
s->sub.decode.codes = c;
but s->sub is a union, and s->sub.trees.blens aliases s->sub.decode.codes
(on the i386 anyway), so the patch completely changes the behaviour.
Could someone seeing crashes since this "fix" try the following
patch?
