Archive from user: Amanuel Wolde-Kidan When using grompp on a system with pull-group1-pbcatom option set to –1 in the mdp file a segmentation fault is encountered. Values of pull-group1-pbcatom = 0 work. The option pull-group1-pbcatom = –1 works in gromacs 2018. A simple water box test case is attached. *(from redmine: issue id 3023, created on 2019-07-04 by gmxdefault, closed on 2019-08-22)* * Changesets: * Revision 457d046bd141a7258cfda4614a23709d911adaab by Berk Hess on 2019-07-29T11:45:34Z: ``` Fix segmentation fault with cosine pulling Both grompp and mdrun would fail with a segmentation fault when using cosine-weighted COM pulling.
