[gmx-users] Ewald sum.

[Lala]

 Hello.
When I set Ewald sum as a coul. type in grompp file
and then run mdrun, it crashes 
and dumpes core. So it does with PME, PPME
switched on. But goes normaly with coul. type "Cut-off". Why?
I run GMX on OpenBSD. During compilation 
i've got only one error cennected with XDR headers,
and then assebled GMX without thinking about it
( so, now i dont use xtc formats for traj.) 
Can it be the reason for crashing mdrun?
