Description David Binderman 2005-06-30 06:04:08 EDT
Description of problem:

I just tried to compile package gtk2-2.6.7-4 from Redhat
Fedora Core development tree with the gcc 4.0.0 compiler and
the compiler flag -Wall.

The compiler said

1.

gtktreemodelfilter.c:1593: warning: operation on 'i' may be undefined

The source code is

      for (i = MAX (--i, 0); i < level->array->len; i++)

I agree with the compiler. This code would benefit from rework, because
it is wise to avoid doing predecrement on a variable in a macro call.

2.

gtktreemodelfilter.c:829: warning: operation on 'i' may
be undefined

gtktreemodelfilter.c:905: warning: operation on 'i' may
be undefined
