Assertion `numberProhibited_ == oldModel->getNumCols()' failed

[lovasoa]

CglPreProcess.cpp:2492: OsiSolverInterface* CglPreProcess::preProcessNonDefault(OsiSolverInterface&, int, int, int): Assertion `numberProhibited_ == oldModel->getNumCols()' failed.

This failed assertions was reported in the following related issues:

• SOS constraints on continuous variables Cbc#376 (comment)
• Cbc Preprocessing error (Windows only?) jump-dev/Cbc.jl#30

It seems to happen only on problems that contain SOS constraints.

It would be very helpful if you could provide a minimal example that reproduces this issue.
