Dear Amber Users,

  I've noticed a small bug in ambmask (amber9). Launching of ambmask
  resulted in such an error message and the program buzzed:

forrtl: severe (174): SIGSEGV, segmentation fault occurred
Image PC Routine Line Source
libc.so.6 420744FE Unknown Unknown Unknown
libc.so.6 420734D6 Unknown Unknown Unknown
ambmask 08073312 Unknown Unknown Unknown
ambmask 08073379 Unknown Unknown Unknown
ambmask 0804BC9D Unknown Unknown Unknown
ambmask 0804A485 Unknown Unknown Unknown
libc.so.6 42015574 Unknown Unknown Unknown
ambmask 0804A3B1 Unknown Unknown Unknown

My system is RH9, p4, ifort 9.0, mkl 7.2.
Looking through the ambmask.f, I've seen that the error was caused by
the line 265. Here the variable i had the value of (natom + 1).
Replacing of it by natom fixed the problem. The bugfix is attached.

Regards,
Katya
