Comment (by cehoyos):

 I tested the following command line:
 {{{
 $ ffmpeg -threads n -i 00009.MTS -f framecrc -an out
 }}}
 For n==1, I get an identical out file trying several times, for n==7 I get
 a different out file on nearly every run on a (single-core SSE2) Pentium M
 with both git head and 18a7f74 (indicating that this may not be a
 regression or that I see a different problem).

 I was unable to reproduce this issue on a Core-2 Duo.
