Bug 202255

Version:           2.2 (using KDE 4.0.5)
Compiler:          gcc 
OS:                Linux
Installed from:    SuSE RPMs

Calculating E^PI and PI^PI crashes kcalc.

calculating E (using the constant/mathematics menu) followed by function "^" or the x^y button followed by PI (from constant/mathematics menu or from previously storing in memory). Enter (for "=") crashes kcalc.

I checked several variations in the KDE 3.5.9 version, and then checked the KDE 4 version. PI^PI crashes. E^E does not. 3.14159^PI does not.

The KDE 4 version gives this backtrace:

This backtrace appears to be of no use.
This is probably because your packages are built in a way which prevents creation of proper backtraces, or the stack frame was seriously corrupted in the crash.

--end of backtrace.

Since the crash handler claims the backtrace is not useful, I am also including a KDE 3.5.9 backtrace:

System configuration startup check disabled.
