Hitting assertion in threaded cbc run inside ClpSimplexDual

Description

Dear all,

currently I try to test the Cbc solver as an replacement of mine old (commercial) MIP solver. A set of optimizations are done in row (always the same layout, but a different setup, using the Cbc threading feature), but currently I hit the following assertion in the ClpSimplexDual? Method (that's why I post it to the Clp page):

ClpSimplexDual?.cpp:2403: int ClpSimplexDual::updateDualsInDual(CoinIndexed? Vector*, CoinIndexedVector?*, CoinIndexedVector?*, double, double&, bool): Assertion `iStatus>0' failed.

What's the reason to hit this assertion? Is there a way to fix this assertion on the Clp site or must the reason be fixed from the user point of view?

I use the the current stable branch.

Thank you very much for your help.
