to be certain, you would have to report a proper stack trace obtained
with vmd -debug (see VMD docs for details).

there have been a few bugs in the gromacs plugin that crept into the
code with some updated features to it late in the VMD 1.9.2
development cycle. so chances are that this is related. the bugs have
been detected and fixed in the development sources.
