[gmx-users] gromacs error

[Mark Abraham]

Hi,

Yeah I've never seen that, so I assume it's something weird related to how
GROMACS was originally compiled vs how the system has been updated since.
Since a rebuild is the way to investigate that, definitely update to at
least the latest 5.0.x while you do it.
