- NonterminatingLassoResult [Line: 42]: Nonterminating execution
Found a nonterminating execution for the following lasso shaped sequence of statements.
Stem:
[L29] int d = 1;
[L30] int x = __VERIFIER_nondet_int();
[L31] COND FALSE !(!(x <= 1000000 && x >= -1000000))
[L32] _Bool c1=__VERIFIER_nondet_bool(), c2=__VERIFIER_nondet_bool();
[L32] _Bool c1=__VERIFIER_nondet_bool(), c2=__VERIFIER_nondet_bool();
[L34] COND TRUE \read(c1)
[L34] d = d - 1
VAL [c2=0, d=0, x=1]
[L35] COND FALSE !(\read(c2))
VAL [d=0, x=1]
[L37] c1=__VERIFIER_nondet_bool()
[L37] c2=__VERIFIER_nondet_bool()
[L39] COND FALSE !(\read(c1))
VAL [c2=0, d=0, x=1]
[L40] COND FALSE !(\read(c2))
VAL [d=0, x=1]
Loop:
[L42] COND TRUE x>0
[L44] x=x-d
