Re: [gtk-list] Unsolvable bug ...

[Roland Bock <rbock eudoxos de>]

Hi!

2 remarks:
1: It looks to me as if you are destroying and creating too often, you
might want to think of other solutions like using on window for
searching and one for results or one for both at once (MHO from your
description, don't take that too serious)
2: Whenever I have a bug like yours, it is a bad malloc, realloc, free
or the like. I have no receipt yet for finding them, but the number of
such bugs is reduced by some large factor using the g_malloc, g_new,
g_free, etc., as well as the string handling function which are prone to
memory errors, too. I actually find most of the bugs in older programs
of mine by replacing all functions concerning memory by those of glib.
Another possibility is that you accidentally refer to a widget that is
destroyed, when it's parent gets destroyed.

Good luck,
Roland Bock
