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.
