[xine-devel] xine and nvtv segfault

[Achim K. <ma...@ka...>]

Hello there,

For some time now xine segfaults for me when I use nvtvd. It doesn't work
with the latest CVS Version (and several others before). Looking at the code, 
I found something irritating in tvmode.c:

tvmode_connect()
[...]
    if (back_client_avail ()) {
        main_card_list = back_client_init ();
    } else {
        if (this->verbosity >= XINE_VERBOSITY_LOG)
            printf ("tvmode: Nvtvd not detected, make sure nvtvd is
running.\n");
        /* Handle well in some way... */
        return;
    }

    if (back_access) {
        back_access->closeCard ();
    }
[...]

back_client_init() opens the pipe to nvtvd sets back_access and closes the
pipe. Later in closeCard() the pipe is closed again which leads to the
segfault. I don't know why this condition exists, but it works if I remove
it.

I have attached a patch to the latest cvs.
