So far not able to reproduce bug with arki001.<br>
<br>
Fixed first assertion problem. Not very clever of me - if you look at assert message you will see just one = , not == ! So assert only fails if problem has zero rows, but then will always fail.<br>

<tt>Hi,<br>
<br>
during tests we found some issues in the cbc 2.2.2 release packet. They are reported in the trac system<br>
* an assertion `numberRows=basis->getNumArtificial()' fails in preprocessing on miplib2003/seymour (#74 only linux, not windows)<br>
* an uninitialized variable in liftAndProjekt cuts on miplib2003/fiber, sometimes crashes afterwards. There are several if-blocks where that<br>
var is assigned a value. However, some cases in fiber.mps don't fit to any of these blocks. (#76, linux and windows)<br>
* assertion fail in updateDualsInDuals during branch-and-cut on miplib2003/arki001 (#77 only testet on linux)<br>
* crashes with bad_alloc exception on windows (not easy to reproduce, maybe a pure windows issue as no problem on linux) (#75, reported for a1c1s1, but also (rarely) occurring on other instances of miplib2003)<br>
<br>
I will be happy to provide more information if needed<br>
<br>
Thanks,<br>
<br>
Torsten<br>
