Subject: [Coin-contest] sample1 causes invalid assertion in Clp
Message-ID: <Pine.SOL.4.44.0304221145390.22406-100000@icarus.math.mcmaster.ca>

Hi,

It does not look like a very big deal, but I have just observed sample1 of
Sbb causing an invalid assertion in ClpSimplexDual::dualColumn() after the
the search is completed on l152lav:

testit: ClpSimplexDual.cpp:1734: void
ClpSimplexDual::dualColumn(CoinIndexedVector*, CoinIndexedVector*,
CoinIndexedVector*, CoinIndexedVector*, double): Assertion
`oldValue<=dualTolerance_*1.0001' failed.
Abort

Looks like something having to do with Clp tolerances.

Best,
