Linux crashes
tiwag:
meister: i've applied your patch and still get a crash when doing the following:
1. start CB
2. open a simle console "hello world" project
3. do Menu : Project->Close Project
4. if startpage is enabled, a blank startpage appears and the Busy-cursor circulates forever ...
5. do Menu: File->Quit, CB crashes with a Segmentation fault (it crashes regardless of the startpage setting)
the backtrace shows src/src/main.app:86 ( "IMPLEMENT_APP(CodeBlocksApp) " macro )
any ideas how to trace this ?
do you get the same crash ?
linux ubuntu 5.10 breezy, wxGTK2.6.1 unicode shared (from ubuntu repository)
backtrace attached

Der Meister:
This patch was not for any crash.
It fixes the lock-up when Code::Blocks asks if the changed layout should be saved while Code::Blocks is shutting down.
The crash you are talking about is another problem with wxYield. I can reproduce this here, too, and I'm quite sure that it is a plugin-related issue. Here is the backtrace I got when I stopped Code::Blocks after closing the project:

Yet I don't know which plugin causes the problem but I will check it.

i never got this message cause i had disabled (don't annoy again) this dialog,
as i found out after searching a while now ;-)
Der Meister:
OK, some new information:
I can reproduce this problem even if all plugins are deactivated.
Another really weired problem:
If I have multiple files and the "start here page" open and then select the "start here page" Code::Blocks uses 100% of my CPU. But it still reacts and if I select another open file the CPU-usage goes down to normal values. Switching back to "start here page" goes up to 100% again, etc...
This is no problem with wxYield (at least I did not find any call to this function and there is no crash) but it looks as if the menus are continuously updated while the "start here page" has the focus. In combination with a call to wxYiel (as it is the case in the crash tiwag described) this would explain the high CPU load and the crash.

Thanks DerMeister, this looks like a crucial piece of info. Let me see what I can find...
