[Coin-lpsolver] ClpSolve problem

[François Galea]

Hello,

I have met several segmentation fault errors, when I use the 
ClpSimplex::initialSolve( ClpSolve & ) method for starting a new solve.

The example attached program doesn't work, if I choose to switch 
presolve off. If I switch it on, everything works (provided the Clp 
sources have been patched with the patch I sent before, otherwise the 
names changes won't work). Some other pieces of code I've got crash even 
if I set presolve on.

I haven't understood enough the internals of ClpSimplex and ClpModel to 
be sure about what is wrong.

Could somebody tell me what's wrong ?

Thanks,

François
