Gdb hangs when debugging SDL app


I want to use gdb in order to debug a game I am working on. This game uses SDL,
for graphics and inputs things.

It seems that when the video is set using sdl (with SDL_SetVideoMode I guess), a
new thread is created by SDL, and gdb seems to hang :-------------------------------------

(gdb) run -w

After that (I have waited a couple of minutes), the solution I have is to kill
gdb (but my program still stay in memoory, I’m unable to kill it).

If I run the program without debugging, I don’t got something like that. This
part of the program run well.

I’m not sure if gdb has been compiled with thread support (it seems), but I’m
confident in is ability to deal with threads.
So, maybe there is a little tip to use gdb with SDL ?

Any help is appreciated :wink:
