Description Diego Candido 2010-12-15 22:50:59 UTC

Version:           unspecified (using KDE 4.5.1) 
OS:                Linux

When i enter the following series on kalgebra it crashes

Reproducible: Always

Steps to Reproduce:
Enter the following text in input area: sum(probability(5, t, 6, 1, 5):t=0..5)

where probability is defined as: probability:=(place, case, totalprobability, positive, negative)->(comb(place, case)*(positive/totalprobability)^case)*(negative/totalprobability)^(place-case)

Actual Results:  
Application: KAlgebra (kalgebra), signal: Segmentation fault

Expected Results:  
The sum of numbers

Can you try if that still happens if using up to date trunk?

Thank you

SVN commit 1207851 by apol:

Make it possible to _evaluate_ sum's instead of expecting them to be simplified at some point.
