We are running PARIX 1.3.1 on a Parsytec GCPowerPlus with DETOP 1.0 installed
via our own Computing Center Software (CCS).

Some of our users wanted to start DETOP and got something like this:

Error(c0000000)-Node 0, Context 2, Thread 4, Function
_PX_DefaultTrapHandler:
 DATA ACCESS exception:
 illegal access to virtual address #0000001f (Rel.IP:#000361fc /
#03ec847c)
 core dumped to file 'core.n0.c2.t4'
Error(c0000000)-Node 1, Context 2, Thread 4, Function
_PX_DefaultTrapHandler:
 DATA ACCESS exception:

#03ec847c)
 core dumped to file 'core.n1.c2.t4'
Error(c0000000)-Node 2, Context 2, Thread 4, Function
_PX_DefaultTrapHandler:
 DATA ACCESS exception:

_PX_DefaultTrapHandler:

This output turns up only when DETOP is used and the program was compiled with
the -g option. This of course is necessary for DETOP to work correctly.
The same program seems to be ok without DETOP or -g option.

Has anybody got the same output and resolved the problem suggestively or is
there somebody from TU Muenchen (where DETOP was made) here reading this group
and can help us and our users?
