Comment (by stoinski):

 I generated an MPS file for my problem using
 OsiClpSolverInterface::writeMps() and runned this file using both Osi-0.97
 and Osi-0.98 with a slightly modified program basic.cpp found in
 Osi/examples/basic.cpp. I attached the modified version, which primitively
 traces new and delete calls. Comparing the output of this program for new
 and delete, also looking in /proc/self/stat, tasklist.exe or top shows,
 that the memory usage is growing and not all resources are released
 correctly.
 Unfortunally my mps file is quite huge (24MB, 1.6MB compressed) and I
 can't upload it to this wiki page. But I can send it to you any time, if
 you ask.
 Regards
 Daniel
