Hi rooters,

I use TH1::KolmogorovTest(...) to automatically check the output of some 
test Histogramms/Trees on different platforms/systems.
Sometimes (~5% of histos) I get an error message (see below). The 
sourcecode comments:

// This numerical error condition should never occur:

What does that mean? How can I fix it?

OS: GNU/Linux RH7.2 & Solris8
ROOT:  *   Version   3.02/03  16 November 2001   *

Cheers,
Rolf
