foxbase panics sco unix

[Heiko Blume]

i have a problem with SCO FoxBase 2.1 running under SCO UNIX 2.0GT:
while reindexing the databases (biggest ~10MB) with 'pack' the
machine panics with 'trying to free already freed block'.
now i thought this is the bug that causes invalid inode table entries
that should be fixed by unx279, but that didn't help. i even reinstalled
from scratch to be sure to apply the patch to a clean kernel, but
the panic persist. i should note that it doesn't always panic, but
you can sure wait for it, reindexing 2 or 3 times does it.

any pointers?
