OK, that didn't detect anything.  We need to investigate a core.

Do a build with "CFLAGS += -O0 -ggdb".

Does Slackware have the systemd-ish coredumpctl stuff?
I suspect not; so we need to enable suid-coredumps.
  (Over here, Fedora, the hints are in "man core" which mentions /proc/sys/fs/suid_dumpable)
and check that "ulimit" does not restrict the size of corefile.

Run a test to get a crash, and locate the core file.

Run up gdb - "sudo gdb <exim-binary-location> <corefile-location>".
   Ignore all the offers to load debuginfo file for libraries.
   At the prompt:   "bt"
You should get a more comprehensive stacktrace, with file and line number info.


Copy that here.  Keep the corefile; we may want to pull some
variable values out of it.

(If you can do IRC, I'm in #exim on irc.libera.chat)

PS: Slackware is a platform that we don't have coverage for in the buildfarm
     Any volunteers willing to run a buildfarm animal would be welcome.
