You have stumbled over a bug in <span class="application">gcc</span>. Please
<a class="ulink" href="http://gcc.gnu.org/bugs.html" target="_top">report it to the gcc team</a>
but not to us. For some reason <span class="application">MPlayer</span> seems to
trigger compiler bugs frequently. Nevertheless we cannot fix them and do not
add workarounds for compiler bugs to our sources. To avoid this problem,
either stick with a compiler version that is known to be reliable and
stable, or upgrade frequently.
