-------------------+--------------------------------------------------------
Hello,
I have a model with wich CBC 2.6.0 crashes, the system doesn't let me
attach it to the ticket. I'm using the precompiled CBC version available
from CoinAll. I'm not able to compile a newer version so I don't know if
this has been already fixed in the latest version.
The command line used is:
cbc -import crash.lp -solve -solu r.txt -quit
The CBC log up to the crash is:
----------
Cbc version 2.6.0, build Nov 7 2010
command line - cbc -import crash.lp -solve -solu r.txt -quit (default
strategy 1)
Continuous objective value is -0.0845723 - 0.08 seconds
Cgl0003I 0 fixed, 0 tightened bounds, 14 strengthened rows, 0
substitutions
Cgl0004I processed model has 812 rows, 1088 columns (784 integer) and
80015 elements
Cbc0038I Pass 1: suminf. 0.10713 (2) obj. -0.0813099 iterations 218
Cbc0038I Solution found of -0.0810757
Cbc0038I Branch and bound needed to clear up 2 general integers
----------
Just contact me back if you need the model or some further help.
Bye,
