This definitely should not happen. Post your ./configure command line
and output.

The proper way to report crashes is described in the docs and at the
end of each crash is a pointer to that. Please follow the docs and
post a complete gdb trace of mplayer built with debugging info.

There's nothing out of ordinary in the above log except that you're using
an outdated CVS snapshot. I know it's a pain, but snapshot generation
doesn't work currently, so please get a cvs checkout yourself and try
that. The bug may have been fixed already.

Yes, but try a recent checkout first.
