Hello,
I wanted to post this as a reply to a thread on this group called
'How to debug seg fault' but it's past the 30 day mark. The author of
that thread experienced something similar.
I'm getting a bit of odd behavior from my widget program on Ubuntu
5.10. My GUI has a 'File' menu and a toolbar, both of which contain an
'Exit' item which execute the exact same code:
====================
pro _exit, top
widget_control, top, /DESTROY
end
====================
I'm working from the command-line interpreter, not the IDE. Here's the
wierdness:
I compile and launch my program and press the 'Exit' button on the
toolbar. When I try to re-launch the program, my GUI doesn't come up
and IDL exits with only a 'Segmentation fault' message. However, if I
exit my GUI by simply killing the window (clicking the 'X' on the
border), the seg. fault doesn't occur. Also, if I exit the GUI by
selecting 'Exit' from the 'File' menu, the seg. fault doesn't occur.
So I launched the IDE to step through the program and it got much
stranger. I can't reproduce the segmentation fault from the IDE no
matter how I exit my GUI.
Any else seen something like this?
