A make distclean in src/gcc-build solved the issue.

Builds fail reproducible on my machine in the bootstrap comparison step between stages 2 and 3:

@dviktor https://0x0.st/zcUP.txt

@moham_96 Can you please post your error log?

Does this package build ok for you guys ? It fails for me in build()

@dviktor The website is reset now, it's working, before that, it was 500 http status.

@yeahren just checked - download is fine. Maybe your ISP blocking some sites?

ERROR: Failure while downloading http://isl.gforge.inria.fr/isl-0.18.tar.bz2

and https://gcc.gnu.org/pub/gcc/infrastructure/isl-0.18.tar.bz2 is fine

Should be fixed now

@dviktor, sorry for the late response. I don't really use gcc6 anymore and unfortunately I don't have the time to look at this. I've transferred maintainership to you. Good luck!
