Andrew,
The attached patch implements a simple recovery procedure for simplex errors during integer optimisation. This is done by constructing a new basis and and trying to solve the LP relaxation once more. When this happens something like the following is shown:
Error: unable to factorize the basis matrix (1)
Constructing initial basis...
which may not be optimal but I think is acceptable.
