I was just preparing further informations when I failed to gather more insights enabling debug
info in rc.conf when your email arrived.

Yes, I use NanoBSD and build world with these settings:

# Options to put in make.conf during buildworld only
CONF_BUILD='
#CFLAGS=-O3 -pipe -DNDEBUG
CFLAGS=-O2 -pipe -DNDEBUG
WITH_KERNEL_RETPOLINE=YES
WITH_RETPOLINE=YES
MALLOC_PRODUCTION=YES
'

Right now, I commented out those settings and recompile world without RETPOLINE.

Kind regards,

oh
