ffmpeg compilation: "run out of registers" on 10.6.8

[aszoz@…]

While trying to compile ffmpeg I got this error on x86_64 (I was just upgrading ports): Please let me know if more info will can be helpful.

Thanks for the ticket. In the future, please Cc relevant port maintainers.

This looks similar to #37802, but that particular problem only showed up when compiling for i386. Please run the following; if it still fails, attach the entire main.log, which will be mentioned in the failure message.

sudo port clean ffmpeg && sudo port install ffmpeg
