Description David Binderman 2005-07-02 09:45:42 UTC
Description of problem:

I just tried to compile package kdelibs-3.4.0-6 from Redhat
Fedora Core development tree with the gcc 4.0.0 compiler and
the compiler flag -Wall.

The compiler said

KDGanttMinimizeSplitter.cpp:955: warning: operation on 'p' may be undefined

The source code is

	for ( ; offs < end - 1; offs += *offs++)

I agree with the compiler. offs gets incremented and added to, without
a sequence point between the operations.

Suggest code rework.
