Well, if the use of the mmxext flag leads to instructions in |
10 |
the compiled code which the cpu does not have, then CRASH. |

But the SSE instruction sets supersede MMX (and mmxext) and so the |
13 |
mmxext flag is really unnecessary on Core i7 and many newer processors. |

(Ffmpeg may have reasons for still using MMX but I don't know.) |
