Component:  Couenne     |    Version:
 Keywords:              |
------------------------+----------------------
 Minimal working examples are attached.

 When the objective function multiplies a variable by itself, Couenne
 crashes with:

 `CoinPackedVector::setVector`
 `duplicate index`

 When this is replaced with the square of the variable, Couenne solves
 successfully.

 Bonmin solves the example without issue.
