Christian,

The signal 10 dumps a core file, so could you run dbx on the file. Do 
% file core
to see if it's pqsurf core. I think the syntax is 

% dbx pqsurf core

where


This should show the problem.  Otherwise, if I could get the core file to
do some debugging.  Is this a 32 bit build? Any other info would help,logs
Also, are you sure that the pqsurf file was replace?  I'm on vacation
tomorrow, so I'll look at it Monday.   If you need, you can us the pqusrf
from the LDM 5.1.4 distribution with the LDM 5.2 release.
