[gmx-users] trjconv and "Floating point exception"

Using trjconv -f traj.xtc -o confout.gro -dump 15000000, I routinely
get the following error:

Select a group: 0
Selected 0: 'System'
Reading frame       0 time    0.000
Precision of traj.xtc is 0.004 (nm)
Using output precision of 0.001 (nm)

Back Off! I just backed up confout.gro to ./#confout.gro.1#
Reading frame   17000 time 5100000.000   Floating point exception (core dumped)

What is it because of? Insufficient memory? Or something with the
trajectory file (it works nice if "-dump 200000"). The traj.xtc file
is 11GB, the memory is 64GB.
