That is a fine bug report. You just need to put it in bugzilla if you

file is a cut down and modfied version of the class used in Dirac.
I compiled it using the following options:
g++ -mmmx -g -O3 test_mmx_diff4.cpp
The run time comparison is attached to this email as well.
Hope this helps.

3.4.3) give a speedup of approximately 30% when the mmx optimisations
are enabled. However with gcc-4.0.0, the performance of the Dirac
encoder with MMX opts enabl
