gmx bar fatal errors write garbage values
Once upon a time,
gmx bar had a struct with a
double lambda that was fine to pass to a
printf("%f") in a fatal error in (say)
lambda is now a pointer to some kind of struct and the fatal errors print whatever junk is the result of converting the pointer.
Fix formatting of fatal errors in g_bar
The lambda value has changed from a floating
point number into a complicated vector, so we
now have a small routine that formats the contents
of this vector for the fatal error routines.
