Description

The attached tpr produces a SEGV when running 4.0.7 with particle
decomposition. The crash happens in mvdata.c in line 222:

case estLD_RNG: if (state->nrngi == 1)
nblock_abc(cr,state->natoms,state->ld_rng); break;

apparently directly in the gmx_bcast the macro expands to.

md-3eam-3_disre1_ext.tpr (10.9 MB) md-3eam-3_disre1_ext.tpr tpr that produces the crash Carsten Kutzner, 02/02/2010 01:22 PM

Do you have an example tpr file and command line?
With a simple test system it works for me
and I don't get valgrind warnings either.
