6.84/2.57	Proved nontermination with the following witness:
6.84/2.57	
6.84/2.57	State #45 with references set to {}.
6.84/2.57	Nondeterministic instruction %1 = alloca i32, align 4 in node #45 yields value 1.
6.84/2.57	Nondeterministic instruction %i = alloca i32, align 4 in node #46 yields value 8.
6.84/2.57	Nondeterministic instruction %2 = call i32 @__VERIFIER_nondet_int() in node #48 yields value (-16).
