[FFmpeg-devel] [PATCH] Fix unaligned access in lcl decoder

[Jeff Downs]

FATE test 289 (http://fate.multimedia.cx/index.php?test_spec=289) 
currently crashes on Sparc/Solaris due to unaligned memory accesses in the 
lcl decoder.

Attached fixes by using memcpy instead of integer copies on platforms 
without fast unaligned access.
