If I switch to default/linux/amd64/17.0/no-multilib/hardened, emerge gcc and emerge luajit, then rspamd[jit,torch] doesn't work correctly: # /usr/bin/rspamadm configtest -c /etc/rspamd/rspamd.conf PANIC: unprotected error in call to Lua API (5) After switch to default/linux/amd64/17.0/no-multilib, recompiling gcc and luajit rspamd works correctly. Reproducible: Always Portage 2.3.49 (python 3.6.5-final-0, default/linux/amd64/17.0/no-multilib/hardened, gcc-7.3.0, glibc-2.26-r7, 4.18.0+ x86_64) [46/1945]

It's not problem with hardened profile, flag "-fno-asynchronous-unwind-tables" is responsible for problem with lua jit.
