This is more of a report than anything else, but we've found mod_ruid2 doesn't play well on Debian 9.
Until we find some other fix, current solution is to use php-fpm, instead of mod_php, and mod_ruid2, which has the added benefit of letting apache use mpm_event, instead of mpm_prefork (requied for mod_php).
So if you're testing with Debian 9, run this:
I'll change the default in the setup.sh for now.
If we find a solution or more info on the problem, we'll update or fix whatever it is that's causing it.
If anyone else knows, let us know
Current httpd segfault trace:
once we have more time, we'll try and compile mod_ruid2.so with the -g flag to gdb gives us more info about where in ruid_set_perm() function it's segfaulting.
