Could you please do the following:

% ulimit -c unlimited
% whatever is required to produce the "segmentation fault" above

then you should have a 'core' file in the directory (or 'core.14534'
where 14534 is the id of the process). This is what the 'ulimit'
command tells the system to do i.e. produce core files arbitrarily
big. The core file is a dump of the memory used by the process when it
crashed. This allows to do 'post-mortem debbuging'. The core file is
not human-readable but a debugger such as gdb will know what do with
it.

To use gdb do

% gdb gfsview2D core
gdb> where

which will tell you where in the code the 'segmentation fault'
occurred. Just cut and paste the gdb output and send it to me. thanks.

Stephane
