[oi-dev] /usr/libexec/dovecot/anvil crashes immediately

Sent this already to dovecot mailinglist without response so far. Maybe 
someone reading this list can help. Unfortunately it did not show up 
during the test run of the package and I used earlier versions without 
this problem.


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

gcc_OPT = -g
