Hi all,

I am using Qt3 to develop GUI program. In my program, I provide some toolbars and when user click on it, a window will pop up. But there is a strange behaviour happened. When I clicked on the toolbar, the program crashed and showed "segmentation fault" error. By using gdb, I found out that this happened whenever QWidget::show() executed.

The error happened when I use Qt3 library from my own compilation and running on Debian etch. When I use the Qt3 library provided by Debian Etch, the problem occurred occasionally and unpredictable. But when I use Qt3 library from my own compilation and running on Ubuntu Breezy, the error never occurred.

Has anyone experience problem like mine? Any hints will be appreciated.
