Odd. By default the variable switchOffIfLessThan_ in a CbcCutGenerator is zero. This means that you would not get to 9401 as it would fail test -<br>
<br>
if (generator_[i]->switchOffIfLessThan() < 0) {<br>
<br>
at line 9398.<br>
<br>
What value is switchOffIfLessThan_ when assert happens? You do not reference CbcCutGenerator so how is the generator being added to CbcModel?<br>
