Hi,
For about one week I am not able to run the latest CVS
mplayer anymore. It builds fine, but when running it,
it segfaults on startup without _any_ output at all.
I know that I'm running lots of pre-release, alpha
and beta stuff, but since older versions of MPlayer
work just fine, I can't understand why it won't even
startup correctly.
Setting a breakpoint in main in gdb and running it
afterwards, makes it segfault immediately.
I included info about my system and the output of the
gdb script at the bottom of this e-mail.
With friendly regards,
Takis
