/usr/libexec/dovecot/anvil crashes immediately

Dear list,

I built a dovecot package for openindiana (which is a Solaris derivative) from latest version 2.3.18. Everything compiles and builds fine without any issue. Even subsequent installation and startup of main dovecot process works as expected. But execution of /usr/libexec/dovecot/anvil immediately crashes. To get some more meaningful backtrace I compiled with -g. Below some facts of my environment and a backtrace. Maybe some of you are more familiar with this kind of issue as I, and can give some hint or share ideas how to nail down the problem. Or can it be a configuration issue? BTW it is running in a so-called zone. And former versions, I don't know exactly but I believe up to 2.3.17, did not show this crash.

gcc --version gcc (OpenIndiana 7.5.0-il-0) 7.5.0
