[Coin-bcpdiscuss] BAP question

[Matthew Galati]

Hi Peter,

I am sorry that the discussion list is not as active as you might hope. 
In the future, if your question is not answered by bcpdiscuss, you 
should try the general coin discussion list. There are only a few people 
on this list, but many on coin-discuss.

I was able to repeat the error. It looks like the dual vector (pi) is 
NULL at the point where it crashes. Last time I tried this (over one 
year ago), it was working fine. So, something must have changed in BCP 
or CLP. When I have some time, I will debug it and get back to you.

Thanks,
Matt

Yes the example is right one from the link. And I am using Linux,
By looking at the par.par file, it is using AAP_datafile  
../Data/small/6.1.aap.
The reason I didn't put the question to the discussion list, no one 
answers my previous questions.
 
Thanks,
 
Peter.
