Hi Iggy,
The TraceFile seems cut too short, normally there is quite a bit more information leading up to the segmentation fault (or other error). Can you confirm that the very last thing suma writes out in the trace mode is:
-----SUMA_RegisterEngineListCommand [5]: EXIT (file=SUMA_ParseCommands.c line=1343)
** Memory usage: chunks=378 bytes=65318602
Whatever information the trace gave me was not enough to find the error yet.
Does this problem occur on Slackware EACH time you have a node that is not part of any triangles?
cheers,
