> ./configure
> make
> make install{quote}
> After setting up some very minimal configuration, asterisk just works. However, the moment I set the autoload directive to 'yes' in my modules.conf I get a segementation fault while starting Asterisk.

> Please let me know if there's anything else I can do to help reproduce or debug this issue. Perhaps there's a very logical explanation, but I figured a segmentation fault is not what should happen nonetheless ;)
