James E. Conley writes about a way we found to crash a DSP-90
or at least cause tcpd to segmentation fault, by using "wbak".

If anyone's interested, it can be narrowed down further.

"wbak -f 1 -stdout /sys/drivers/ecmb/ether_int.lib >/dev/null"
will cause our tcpd to die, with a segmentation fault.
We ran tcpd with the debugging option and it didn't
produce any obvious information.

We've let Apollo know about this problem, and they are working
on trying to reproduce it.
