Francois,
Can't really see how it happened recently, but anyway I have changed a
default so it should go away.

[Coin-lpsolver] Memory leak in
11/21/06 12:52 PM Clp/branches/devel
I don't know if Clp/branches/devel is active or not, but it seems that
there is a memory leak in Clp there. Running:
for(i=0; i<10; i++) {
OsiClpSolverInterface *clp = new OsiClpSolverInterface;
clp->readMps("seymour.mps");
clp->initialSolve();
delete clp;
}
where seymour.mps is the standard MIPLIB file, the memory usage increases
regularly (this does not happen with Clp1.3.3). Valgrind sees many leaks,
but I don't know which ones are real (the report below is for one loop
only):
