Consider the code:<br>
<br>
OsiClpSolverInterface *clp;<br>
<br>
// A<br>
<br>
clp->messageHandler()->setLogLevel(0);<br>
<br>
// B<br>
<br>
clp->initialSolve();<br>
<br>
// C<br>
<br>
If you print<br>
<br>
clp->handler_->logLevel_ and clp->modelPtr_->handler_->logLevel_<br>
<br>
at point A, both are 1. <br>
At point B, the first one is zero and the second one is 1<br>
At point C, both are 1.<br>
<br>
Obviously, initialSolve() should not modify the logLevel set by the<br>
user. The problem is that setLogLevel() modifies only<br>
clp->handler_->logLevel_ and initialSolve() looks at<br>
clp->modelPtr_->handler_->logLevel_ when saving the logLevel.<br>
<br>
A ticket has been filed (ticket #65).<br>
