[Scip] objdelta infinity

[Jacob Spönemann]

  Hello everybody,

I'm currently implementing a simple column generation approach in SCIP. 
In each round I simply add the variable with lowest reduced cost out of 
my pool of variables.

At some point I'm getting the following assertion failure:

"Assertion failed: !SCIPsetIsInfinity(set, objdelta), file ..\history.c, 
line 144"

Maybe someone could tell what is causing this problem.

Thank you very much in advance.

Best regrads,

Jacob
