- NonterminatingLassoResult [Line: 23]: Nonterminating execution
Found a nonterminating execution for the following lasso shaped sequence of statements.
Stem:
[L18] unsigned int x = 1;
[L19] unsigned int y = __VERIFIER_nondet_uint();
[L21] COND FALSE !(!(y > 0))
Loop:
[L23] COND TRUE x < y
[L24] COND TRUE x < y / x
[L25] x *= x
End of lasso representation.
RESULT: Ultimate proved your program to be incorrect!
