[gmx-developers] segfault in mdlib/qmmm.c

[Åke Sandgren]

Hi!

I have an input set that makes gromacs segfault in qmmm.c when compiled
for mpi.
The segfault is in init_QMrec on the
qm->nelectrons       += mtop->atomtypes.atomnumber[atom->type];
atomnumber is NULL.

Where is the bug? On that line or somewhere else?
I.e. is it a bug that it is NULL or that it isn't protected against that
possibility?
