Memcached crashing on FreeBSD

Woops, I knew that I was going to fumble that one somehow!
The file /etc/malloc.conf does not exist on my system. If I'm reading the
man page correctly it's not actually a file with contents, but a symbolic
link referencing the values. Such as what would be produced by:
ln -s 'ax' /etc/malloc.conf
I was trying the direct assignment inside a .h file before, it works fine
when added to main(). Compiler doesn't recognize FREEBSD, it does like
__FreeBSD__. I added the following just above the settings_init call in
_malloc_options = "ax";
I have recompiled and have this running.
