[Cbc] Segmentation fault with my problem (2.8.3)

[Stefan Vigerske]

Hi,

the issue from
http://list.coin-or.org/pipermail/cbc/2013-August/001141.html
has been fixed and the fix will be in the next release.

You could check out a pre-release (aka bugfix branch aka stable branch) 
via svn by doing
   svn checkout https://projects.coin-or.org/svn/Cbc/stable/2.8
