systemd-coredump[25256]: AT_NULL terminator not found, cannot parse auxv structure.

Hi!

 

I have an issue where Perl dumps core for no obvious reason, and I noticed the line

systemd-coredump[25256]: AT_NULL terminator not found, cannot parse auxv structure.

In the journal.

 

Can anybody explain what it actually means? System is SLES12 SP5 on x86_64 (systemd-228-157.60.1.x86_64).

 

Context is like this:

 

Aug 27 10:41:11 abcdefgh systemd-coredump[25256]: Process 24393 (perl) of user 1025 dumped core.
