I am using OsiClp in a normal manner. Load problem, solve, add some columns, resolve, etc... Periodically, I want to get the basis header. I get the following assertion failure. Do I need to do something special to get basics? There is no error message, just a failed assertion.<br>
<br>decomp_gap: ../../../../Osi/src/OsiClp/OsiClpSolverInterface.cpp:6071: virtual void OsiClpSolverInterface::getBasics(int*) const: Assertion `modelPtr_->pivotVariable()' failed.<br><br>
