gdb /usr/local/sbin/lightdm /lightdm.core

Since about May 5th, lightdm refuses to run with error signal 10.  

I have seen this problem with 11.3-PRERELEASE installed today
(05/23/2019). Package repository is FreeBSD.

I have seen this problem with 12.0-STABLE installed as recently as last
week (05/17/2019). Package repository is local (poudriere).

I have seen this problem with 13.0-CURRENT installed as recently as
last week (05/17/2019). Package repository is FreeBSD.

If I "pkg add -f" from an archive dated 04/24/2019 everything
works as expected.

I have dump output which is attached.

The suggested/required change to /etc/login.conf has been in place for
about three months.

Thank you for the report David.

If you have access to packages later than 04/24 but before May 5th that could help narrow down the time window, that might be handy.
Comment 2 David.Boyd49 2019-05-26 16:05:28 UTC
I don't have the package archive, but I had lightdm installed on 5/2/2019 working on one of the systems.  Unfortunately, that system has been reloaded and the version of lightdm is later than 5/5/2019.

  x11/lightdm: Update to 1.30.0, fix crash and change default config

  This update addresses a crash in lightdm, related to the way the
  user environment for the lightdm process is setup in src/process.c.

  The configuration option in lightdm.conf for locked memory is now
  honoured - the default configuration has been updated to disable this,
  and pkg-message has been updated to reflect this change.
