sc-r-power = 48 leads to segfault
Using Michael Shirts ethanol solvation example from the Virginia tutorial. Power 6 works fine.
Fixed sc_power==48 crash in single precision
A few summation variables in the free energy kernel
need to be double to avoid overflows for 48th power
Fix single-prec. softcore issue in 4.6 branch
This is a backport of 412e2974 which we likely
forgot to put in 4.6. It primarily fixes
numerical issues in single precision for
sc_power==48, but it can also improve stability
of lower-power softcore free energy.
This should not be merged into 5.0 or master.
