Description

When using the membed functionality in mdrun, a segfault occurs after selecting the relevant groups.
The issue seems to be present since at least the original 2019 release and is still present at release-2019^HEAD.

Commands to reproduce

gmx mdrun -nt 1 -s gmembed.tpr -membed gmembed.dat -c pi_pH70_popc_further_solvate.pdb -mn index_before_gmembed.ndx -v

select group 1 for protein
select group 13 for POPC
