    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();

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!
