#81: Hitting assertion in threaded cbc run inside ClpSimplexDual

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.
