When a frozen configuration file exists, and sendmail (5.64 with
IDA enhancements) is run with the -d debug flag, the process
stops and dumps core (memory fault). e.g.:
    sendmail -d -v -bv foo
	Version 5.64+
	setoption v=
	setoption c=F
	setoption d=
	ksh: 15597 Memory fault

This doesn't happen if 1) vanilla 5.64 is used, or 2) no frozen
configuration file exists.  A preliminary investigation revealed
that malloc complains about an apparent corruption of the heap;
5.64+ seems to call malloc and free a few times more before
freeze than does 5.64.

I'm still investigating, but as there are no doubt many
differences in implementation of malloc(), I wondered if anybody
else could confirm this problem.

Please reply via email; I'll post a summary.

Thanks,
