Hello there,
I’m having crashes (segfaults) in SDL_cocoakeyboard.m in latest SDL 1.3, I’ve checked the Bug tracker at www.libsdl.org but it doesn’t seem to be very alive. Should I post bugs there? Or I could do that here as well?
thanks,
Pavel

This happens always on MacOSX version of SDL 1.3, when I open About Application dialog and press any key, it will crash like this. It happens also when switching keyboard layout, I can send a backtrace when this happens again.

there’s a patch but it’s not completely fixing the bug (causes another
crash and doesn’t work on iphone)
you can either wait tor the devs to fix it or dive in the beauty of debuggin

As Vittorio G. pointed out, it’s a known bug that we intended to fix.
However it’s still unclear what caused the 0x0 keyboard->focus, that’s
why I wish I can reproduce it. Is there any chance you can reduce it
to a minimized sample? Meanwhile, you can use the patch posted as a
temporary fix.
Hello,
ok I will give it a try with this patch. I could send a small example
program that crashes, but it’s not written in C but in freepascal.
Basically it will always crash when a key press occurs in a window
that is not created by SDL (for example About Application dialog) and
sometimes when switching keyboard layouts…

Hello Jiang,
I tried the proposed patch and it will fix crashes. When there’s
foreign window not created by SDL, it will properly push events that
report windowID==0 …
I will play with it a little bit more to see if there’s another
unusual behaviour caused by this, or any other related crashes.

I see, I think that’s the best we can do here, since these windows are not
managed by SDL. It will be nice if Sam can take a look and integrate this
patch into the HG repo.
It’s in, thanks!On Tue, Apr 20, 2010 at 2:00 AM, Jjgod Jiang wrote:
