[Cbc] Some issues with cbc 2.2.2 release

[John J Forrest]

Torsten,

4) may be a windows issue, there does seem to be some oddities with windows
malloc.

Do errors 1) and 3) occur in debug mode?  With what driver?  If on Linux
and debug mode then I can look into them - although they may have been
fixed in 2.3.

Hi,

during tests we found some issues in the cbc 2.2.2 release packet. They are
reported in the trac system
* an assertion `numberRows=basis->getNumArtificial()' fails in
preprocessing on miplib2003/seymour (#74 only linux, not windows)
* an uninitialized variable in liftAndProjekt cuts on miplib2003/fiber,
sometimes crashes afterwards. There are several if-blocks where that
   var is assigned a value. However, some cases in fiber.mps don't fit to
any of these blocks. (#76, linux and windows)
* assertion fail in updateDualsInDuals during branch-and-cut on
miplib2003/arki001  (#77 only testet on linux)
* 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)

I will be happy to provide more information if needed

Thanks,

  Torsten
