I'm running NAMD 2.8b1 for Win32-multicore (Built Sat Mar 26 11:16:14 CDT
2011), so this fix should already be included.
I tried adding oneSiteSystemForce to the dhedral (phi) definition, but
without success.
I also find it strange that metadynamics simulations with the same colvars
also crash, although after a much longer period and much less spectacularly--485b397dd0b9f3f49e04a17db91a--
