>Description:
Goto /usr/ports/lang/gcc40, then "make build" or "make install". Building gcc40 will fail:

gmake[1]: Leaving directory `/usr/ports/lang/gcc40/work/build/gcc'
Comparing stage2 and stage3 of the compiler

>How-To-Repeat:
It doesn't matter if gcc40 being installed or not. Just go to /usr/ports/lang/gcc40, then "make build".
