You'll only get a core file if the current working directory of the
process is writable by the process.  Normally.  There are various
sysctls you can use to affect core-dumping:

kern.corefile: process corefile name format string
kern.coredump: Enable/Disable coredumps
kern.sugid_coredump: Enable coredumping set user/group ID processes

See core(5). It is possible to set kern.corefile to an absolute path --
eg /tmp/%N.core -- to always record corefiles in a writable directory.
Also, look at setrlimit values for the maximum size core file permitted.

	Cheers,

	Matthew
