Summary:                    [patch] GCC 4.2.x optimizations result in improper
behavior of GSM codec
Description: 
Two patches were originally reported in bug 11243, one to add additional
needed constraints on some asm() sequences that the codec uses, the other
to disable optimization that the compiler was doing which was resulting in
incorrect code.

Only the latter was committed.  It's been confirmed that both patches are
needed, at least until the code is restructured to allow correct
optimization by the compiler.
