Hi,
i'm trying to do some calculation but i can't get my result converged under
10e-4 , not even 10e-1sometimes, because of an annoying error: SEGMENTATION
FAULT.

I know it's a pretty general error but i don't know nothing else about it. Not
even how to find out what generates it.

I tried the same calulation on two different PC's (AMD Athlon 64 bit 3.5 MHz,
and AMD Athlon 64 4800+ dual core with 2Gb of RAM)
and with different version of ABINIT 5.3.4 and 5.4.4

I'm using HGH pseudopotentials.
My calculation was on LaNi_5, the max Ecut handled is 120 Ha (256 mb of
occupancy) when i try with 140 Ha the calculation stops and i got the error
message in the shell.
I got the same outcome with Dy at 160 Ha or (alpha)Cu_5Dy at 140 Ha ( this
happens also with TM psp).

I've also checked that the segmentation fault error doesn't occur always at 
the
same time if i rerun the calculation.

I hope you could sugget me some ways to give you more specific infos, or how 
to
fix it.

Thank you
