Is the testsuite exercising network functions?  The crash backtraces 
pointed the proverbial bloody finger at the network code.

Lucas Yasuda also mentioned that the system had not been updated in some 
time and the bug report I had found with similar symptoms had resulted 
in a commit, so the bug may be fixed now.

The testsuite runs should probably continue, after all, the kernel 
should not crash no matter what user programs do.  If the Free Pascal 
testsuite is reliably crashing the FreeBSD kernel, then you have a 
reproducer for a FreeBSD kernel bug.
