Application: kcalc (2.7)
KDE Platform Version: 4.5.5 (KDE 4.5.5)
Qt Version: 4.6.3
Operating System: Linux 2.6.34.8-68.fc13.x86_64 x86_64
Distribution: "Fedora release 13 (Goddard)"

-- Information about the crash:
- What I was doing when the application crashed:
I generated 6!, then did the factorial of that (720!).  I then tried to take the cube root of the resulting number, and kcalc crashes.

The crash can be reproduced every time.

-- Backtrace:
Application: KCalc (kcalc), signal: Aborted
