gfortran (from gcc) fails to compile software with error: "suffix or operands invalid for movq"

[viniciusferrao]

Hello guys,

I'm running Brew on El Capitan 10.11.1 and gfortran fails to compile anything with the following error:

/var/folders/yj/b1db0bcx0zvbyblrv354hd6m0000gn/T//cchNg0Pw.s:10704:suffix or operands invalid for `movq'

I'm running updated home-brew: dc5a7e7, and running this version of gcc:
gfortran -v
Using built-in specs.

Can you give us a short set of steps to reproduce the behavior, as well as your brew config and brew doctor? Thanks!

Hello dunn, I really feel dumb right now. The fix to the problem was in brew doctor, it was a non successfully removal of MacPorts. Sorry for submitting an invalid bug.

No worries, glad you figured it out!
