2008-07-16 14:33:17 [wxpython-users] My app crashes on Windows, but not on OSX.
Up until today, the code I have written on my PowerBook has performed
flawlessly on Windows too. I don't have a windows box to test on, so rely on a friend who has a Vista box. My most recent iteration of code works just fine for me, but when he gets it he can make it crash, a hard crash, no traceback no anything, and I have no idea where to start debugging this process. I'm using a Notebook and have some widgets on Tab 1, that affect the content of Tab 2. The crash occurs when clicking on Tab 2. Does anyone have any ideas on how I should go about tracking this down? -- Stand Fast, tjg.

If it were me, I would probably try to figure out which widgets are known to
have inconsistencies between platforms and check over the code for those... but obviously something has to have changed if things stopped working, so tracing back what could have changed (i.e. in your code, or especially in your friend's box) could be what you need to do... paul On Wed, Jul 16, 2008 at 2:33 PM, Timothy Grant <[email protected]> wrote: > Up until today, the code I have written on my PowerBook has performed > flawlessly on Windows too.

I know what changed as I'm adding new functionality. Situation gets a bit
funny though. I took my PowerBook down to his office and said "See it works for me." and showed him just how well it worked. Then he said "Let me try." So I let him try and he's managed to make it break on OSX, and I can replicate the problem. It just needed to be exercised more thoroughly on OSX than it did on Vista. Immediate crash on Vista, not so immediate crash on OSX. So now I'm trying to figure out why my abuse of a wx.Grid is causing a segfault.
