SDL crashes

[scottmc]

While running some games and some of the SDL tests, they will crash out to gdb.

This is from running testgl and then moving the cursor outside of the SDL window:

Huuum

It seems that this bug only affects LibSDL gcc2 version

haikuporter -c -i --test libsdl-1.2-hg

And if the SDL_sysevents.cc file was patched with libsdl-1.2-hg.patch

I ran a couple of tests and see that with SDL_sysevents.cc patched the occours the libsdl gcc2 #457 bug

http://ports.haiku-files.org/ticket/457

If not, if only SDL_BWin.h was patched, all works fine, even 3D games, like DreamChess?

For GCC4 version, has no difference. Everything works fine.

Seems that is not GL fix that was broken: is SDL_sysevents.cc fix

fixed in r1300.
