It has been resolved. Any code using this function should have crashed.

Fixed bug in gmx_sumf_comm where a double array was passed to an MPI 
function expecting a float array.

Now after the next crash:

Fatal error:
Can not find an appropriate interval for inter-simulation communication, 
since nstlist (5), nstcalcenergy (5) and -replex (2500) are all <= 0
