[Cbc] Cbc exiting with error status

[Vishist Mandapaka]

Hi,
 Environment:
Ubuntu 10.10 (32 bit)
Cbc: 2.4.0

When I'm trying to solve a model with Cbc through pyomo (a sandia labs
python redirection), cbc is throwing an error.
It used to work earlier, but when the size of the model got increased due to
constraint set, it didn't work on 32 bit OS.

Here is the error log:

I'm not sure what could've caused this. Appreciate your time reading through
this, and please let me know if changes are required.

thanks
