Yes, you are running OLD Toronto version.

Yes and no, more of the gory war-story once I get the coredrop
eradicted (possibly GCC problem.)

What do you mean with "5.4 flags" ?
GCC-2.5.6 (soon 2.5.8, I hope) natively, and cross
compiled on SunOS 4.1.3. Both seem to work aside of
native one crashing on some IO-buffer fault in stdio-lib
(gcc-2.4.5) when processing a mailinglist with more than
4k characters in the list-file. (Binary-compability mode
run version from 4.1.3 works just fine on same input!)

Have you heard of what there was before comp.os.linux.* newsgroups ?
THAT was run on Zmailer once they got fed up with old sendmail
trashing whole system... (and it still is run on the Zmailer..)
Current Zmailer source has kludges to circumvent Sony NEWS defficiencies
on rename(2) system call. Zmailer (scheduler usually) was able to
crash that machine just by doing frequent rename()s..

There is "yours truly"'s collection.
New version comes in, once I stop answering your email and start doing
