Dear List,
I get a segmentation fault running the examples/USER/misc/srp/in.srp script using the most recent LAMMPS version from 9/1 2017. Both code and script without modifications. It runs for the stable_17Nov2016 version. The error is:
:
Removed/inserted 0/2700 bond particles. (../fix_srp.cpp:249)
Extending ghost comm cutoff. New 3.523044, old 3.000000. (../fix_srp.cpp:271)
