If you are a sporadic contributor, the easiest and cheapest way to work on GCC
is to get an account in the compile farm: https://gcc.gnu.org/wiki/CompileFarm
and use one of the many scripts in contrib/ (or my own gccfarming script:
https://gcc.gnu.org/wiki/ManuelL%C3%B3pezIb%C3%A1%C3%B1ez?action=AttachFile&do=view&target=gccfarming)
to bootstrap and regression test patches.

i've verified that 4.8.0 & 4.9.1 fail as well :/

binutils 2.24 doesn't help
