[wx-dev] SetShape from trunk crashes under Leopard, was Re: [wx-dev] wxMac: URefCon not defined

Tue Feb 12 01:47:40 PST 2008

I installed the newest update (10.5.2) from the Software Update menu,
but that didn't seem to help (at least not for my program). The shaped
sample compiles & runs fine now (I can start it and it doesn't crash,
but I'm working via SSH, so I can't see if it runs ok of course :) -
I'll see tonight when I get home).

$ xcodeindex -version
Component versions: DevToolsCore-921.0; DevToolsSupport-893.0

$ xcode-select -version
xcode-select version 895.

$ xcodebuild -version
Component versions: DevToolsCore-921.0; DevToolsSupport-893.0



As for the crash: please check the backtrace. There you see it still
crashes in the SetShape() call.

This should immediately show the shaped window, but it also crashes:
