...means that every Wx::Bitmap (for example, and others) are always marked in ruby''s GC mark phase, so they are never collected until shut down, even if they have fallen out of scope everywhere else. I think the way to go is to dispense with fixdeleting altogether and define appropriate freefuncs for the different types of Wx classes (Windows, TopLevelWindows, Events, others) that reflect wxWidgets own memory management tactics. But this uncovers quite a few bugs that have so far been masked, so I think we should try after releasing 0.0.40 alex

...eing notified of its destruction at the right time, so I tagged the ruby object that it now pointed to nothing, and then checked the ruby object, which still hangs about, at exit cleanup. I''m not sure whether this is a wxWidgets oddity, or whether it''s because SWIG''s %freefunc doesn''t play well with directors yet. Either way, it may (or may not) illuminate some of the other random crashers on other platforms. alex -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

It has been a frustrating couple days. I have been tracking down the bug where any wxruby-swig app will crash/segfault upon exit. Yesterday, I fixed the problem where the App object was being freed twice. Today, after several hours of debugging, I discovered that the Frame object is also being deleted twice (for a different reason). I have asked Lyle Johnson for some guidance, because it is
