You don't have to rebuild your kernel to raise the maximum data
segment size.  Just set kern.maxdsiz in /boot/loader.conf and
boot with the new setting.

Increasing kern.maxdsiz and checking that the user limits are not
still set to 512 MB may help a bit, but if the program still
tries to allocate enormous amounts of memory I'm not sure if this
is going to help a lot.
