Summary: Bug: isInSubset
Initial Comment:
Hello,
the function isInSubset in ql/models/marketmodels/utilities.cpp crashes in some cases.
Subset loop:
while (true) {
subsetElement = subset[j];
result[i] = false;
if (setElement < subsetElement) break;
if (setElement == subsetElement) {
result[i] = true;
break;
}
if (j > dimsubSet-1) break;
++j;
}
The largest allowed j in the line with the break is j==dimsubSet-1. In the next line j is increased by 1 and we have j==dimsubSet. The next statement at the beginning of the while-loop will exceed the array-boundary:
subsetElement = subset[j].
I think a greater or equal would be a solution:
if (j >= dimsubSet-1) break;
Kind regards
Jan van Heys
