[Coin-discuss] Cbc crashes when solving this mps file

[John J Forrest]

Esben,

Code was trying to recreate original row indices for processed problem - 
but CglPreProcess had added rows rather than just reducing - don't really 
know why error hadn't happened before.  Row indices were never used - it 
was just a by-product of getting original column indices - which were 
correct.

So I have just moved some code around so just column indices computed. 
Should be OK now.

[Coin-discuss] Cbc crashes when solving this mps file






Hi,

I've create a ticket on coin-cbc. 

https://projects.coin-or.org/Cbc/attachment/ticket/17

The attached mps file crashes cbc on both trunk and devel.

I crashes in the cgl preprocessing somewhere quite quickly.
