[Coin-lpsolver] assertion "last_corrected != -1" failed in CLP

[John J Forrest]

It is fine on development branch "pre" where presolve has been moved to 
Coin section.  I will track down what is the difference.    It is probably 
because it is presolved down to 0 rows and columns.

[Coin-lpsolver] assertion "last_corrected != -1" failed in CLP






Hi,

Trying to solve the small attached "fail.mps", with CLP using :
import fail.mps
presolve on
dualS

I get :
assertion "last_corrected != -1" failed: file "PresolveTighten.cpp",
line 380

It works ok when not using the presolve.

Regards,

js
