[gmx-users] GROMACS 2019: CorrelationsTest and TrajectoryAnalysisUnitTests segfaults on CentOS 7.6

[Åke Sandgren]

The build where we have seen it is with intel 2018.3.222 using GCC 7.3.0
as base compiler and binutils 2.30.

The same combo on Ubuntu 16.04 does not have a problem.

Just wanted to know if it is a known problem or not.
