I am attempting to compile gcc5 on FreeBSD 11.0-RELEASE-p2 on sparc64. The compilation fails during bootstrap comparison. I attempted to compile gcc5 with the default system compiler (gcc 4.2.1) as well as with gcc47 (which built normally); both give the same error. ... ...

I can build both gcc5 and gcc48 as long as I do not select bootstrapping in config.
(In reply to Michał "phoe" Herda from comment #2) > I can build both gcc5 and gcc48 as long as I do not select bootstrapping > in config. If anything, it's actually supposed to be the other way around, boostrapping should be the safer option. The error you see is GCC compiling itself repeatedly does not lead to a consistent result as it should. Clearly this does not happen for other SPARC targets of GCC, and I'm afraid I won't be able to help with this. (Luckily there is at least a workaround of disabling bootstrap, which is the default for lang/gcc.)
Expired port removed.
