I have encountered such a problem: Firefly succefully runs on my older machines with Core2 Quad Q6600 CPU and fails on my newer machine with Q9550. The outputs are the following.

Q6600:
Intel Core2/ Win32  PC GAMESS version running under Windows NT
Running on Intel CPU:  Brand ID  0, Family  6, Model  15, Stepping 11
CPU Brand String    :  Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz
CPU Features        :  CMOV, MMX, SSE, SSE2, SSE3, SSSE3, MWAIT, EM64T
Data cache size     :  L1 32 KB, L2 4096 KB, L3     0 KB
CPU frequency is    :  2405.510 MHz
max    # of   cores/package :   4
max    # of threads/package :   4

Operating System successfully passed SSE support test.

Q9550:
Intel Core2/ Win32  PC GAMESS version running under Windows NT
Running on Intel CPU:  Brand ID  0, Family  6, Model  23, Stepping 10

*ERR* KO-04 integer divide by zero

Does anybody know, the reason is in Firefly, Q9550, or my bent hands?
