Description David Binderman 2005-09-24 07:20:01 EDT
Description of problem:
I just tried to compile Fedora development package kdegraphics-3.4.2-5
with the extra compiler flag -Wall.

The compiler said

kpcursorlightcross.cpp:75: warning: 'colorValue' is used uninitialized in this

The source code is

    if (colorValue)
        colorBitmap [y * (width / 8) + (x / 8)] |= (1 << (x % 8));

There seems to be a missing default section in the previous switch statement.

Suggest initialise the local variable "colorValue" at its declaration
to make the code bulletproof and to shut the compiler up.

Version-Release number of selected component (if applicable):
