Hello Reimar,

thank you for taking interest. OK, I'm aiming at producing the mplayer.bug
file with all the relevant gdb output of the crash as described in the
mplayer docs.

So I create a command file holding these lines:

disass $pc-32 $pc+32
info all-registers

Then I run:

gdb /usr/bin/mplayer --core=core -batch --command=command_file >

But all I get is this:

/home/sk/film/core: No such file or directory.
No stack.
/home/sk/film/command_file:2: Error in sourced command file:
No registers.

This happens with mplayer SVN compiled a minute ago and gdb 6.6 (stock
Gentoo x86 gdb). I still have the first gdb command running, but it
doesn't create a "core" file if thati's what the second gdb command is
looking for.
