[Coin-lpsolver] assertion "last_corrected != -1" failed: file "PresolveTighten.cpp", line 373

[Jean-Sebastien Roy]

Hi !

Using the attached clp-1.mps lp problem, when I do :
# clp -
Clp: import clp-1.mps
Clp: presolve on
Clp: dualS

I get the following error :
assertion "last_corrected != -1" failed: file "PresolveTighten.cpp",
line 373

Solving without the presolve works fine.

Regards,

js
