[Coin-lpsolver] CglLandP and CLpSimplex:pivot()

[Menal Guzelsoy]

Hi,

I have been doing some testing with the new CglLandP generator and for  
some instances I
am getting the following error:

  ../../../Clp/src/ClpSimplex.cpp:6616: int ClpSimplex::pivot(): Assertion
`fabs(dj_[sequenceIn_])<1.0e-6' failed.
Aborted

It seems that ClpSimplex refuses to pivot on the element chosen by  
CglLandP because of different tolerance values used in each project.  
On the other hand,
CglLandP fails to detect it due to termination. If needed, I can also  
send a simple cutting plane alg. implementation to illustrate the  
problem.

Thanks,

Menal.
