Did you try without these (third-party) modules?

This says prefork but gdb traces seem to indicate MPM event (explicit
LoadModule?), which one is used exactly?

This is pretty stable for me with both MPM prefork and event, but without the
third-party modules.

You probably need the .gdbinit file provided by httpd
(https://github.com/apache/httpd/blob/trunk/.gdbinit) in your gdb environment
or working directory.
