I tried compiling mplayer 29411-3 on i686 from abs. However, I got the following error:

Experiences of other users and the solution to the problem can be found here: http://bbs.archlinux.org/viewtopic.php?id=81345

Seems like the new default LDFLAGS break the build. Thus just add "unset LDFLAGS" to the PKGBUILD.

After that mplayer compiles successfully, but it doesn't play Matroska files anymore:

MPlayer interrupted by signal 11 in module: init_audio_codec
- MPlayer crashed by bad usage of CPU/FPU/RAM.
Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
gcc version. If you think it's MPlayer's fault, please read
DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
won't help unless you provide this information when reporting a possible bug.

Again the solution can be found in the forums: http://bbs.archlinux.org/viewtopic.php?id=79119

Adding the "./configure" option "--extra-cflags=-fno-strict-aliasing" lets MPlayer play .mkv files again.

Just filing this for easier reference.
