==> main.fstb MAY NOT TERMINATE. 

Cycle with transition(s):

t1 [A = 8, B = 0, C = 0, D = 0, E = 1, F = 0, G = 0, H = 0, I = 1, A__o = 0, B__o = 0, C__o = 0, D__o = 0, E__o = 0, F__o = 0, G__o = 0, H__o = 0, I__o = 0]
 -> t4 [A = 8, B = 0, C = 0, D = 0, E = 1, F = 0, G = 0, H = 0, I = 1, A__o = 0, B__o = 0, C__o = 0, D__o = 0, E__o = 0, F__o = 0, G__o = 0, H__o = 0, I__o = 0]

is likely to be an infinite loop.
