Warning: Not enough memory to allocate a_graph->arcs - fixed in latest version?

[MediciBrown]

Dear CBC community,

had been using CBC2.10 for a model and got the following bug/warning message that led to the stop of CBC solving procedure:
Warning: Not enough memory to allocate a_graph->arcs
Cannot proceed with 0-1/2 cut separation
Log: SolvingLog_WarningMessage.txt

I could solve the same model with other solvers without problems.

I tested with various CBC versions and noticed that from CBC2.10.3 onwards I could not reproduce the same behaviour and could solve this model correctly.
For example Log from NEOS server using 2.10.10: NEOS_SolvingLog_CBC21010.txt

Does anybody know:

1. Why this warning message occured?
2. Is it something that was fixed for sure in one of the releases 2.10.1-3 or did it disappear "by accident" for this particular case, but might appear in another model?

Thanks for any feedback on this!
