  - NonterminatingLassoResult [Line: 10]: Nonterminating execution
    Found a nonterminating execution for the following lasso shaped sequence of statements.
Stem:
[L6]        int i;
[L7]        int j;
[L8]        i = 0
Loop:
[L10]  COND TRUE   i < 100
[L11]              j = 0
[L12]  COND TRUE   j < 1
[L13]              j = j+1
[L12]  COND FALSE  !(j < 1)
[L15]              i = i+0
