NOTE FOR BASH USERS:
I run modeller and it crashes with this message:
"/bin/mod6v2: line 38: 1874 Segmentation fault
(core dumped) $NICE ${EXECUTABLE} $STEERF >$LOGF"
I used bash and I put the following command line in the .bashrc file as suggested in some messages of the mailing list:
ulimit -S unlimited
It appears that using the -s (lower case "s") solved the problem
mentioned above. -S means Soft limitation and -s for stack maximum.
The correct command is therefor:
ulimit -s unlimited
