The ABINIT Users Mailing List ( CLOSED )

Hi Xuan Luao,

I feel that you may have not understood correctly the comment by Ian
Haiping : You do not give us engouh information so we can't help you.
Most readers of this forum knows exactly what a seg fault is ; yet
that's not the point since Abinit is not so badly written that arrays
have predefined sizes (except for rare exceptions). So in order to
help you most readers of your mail have thought :
- It would be much more informative if this guy has followed the
netiquette  ( http://www.abinit.org/community/?text=netiquette ) and
posted all important informations from stderr, stdlog, stdout, and
stdin ...
- Also, since he knows what a seg fault is he would have helped
himself a lot by doing this with a debug enabled version of Abinit,
has Ondrej Certik suggested.

Best regards

PMA
