--- Comment #8 from Linus Torvalds <torva...@linux-foundation.org> --- Oh, and this is marked as a duplicate of 61801, but that one is marked to be in gcc-4.8.3 The particular problem we see in kernel code generation seems to *not* happen in 4.8.3 (current fedora 20), and happens with Debian 4.9.0. So now I worry about (a) whether the duplicate bug is really true (b) or perhaps 4.8.3 really does have the same problem and we might get bitten there too, and it just happens to trigger on 4.9.0 for some otherwise unrelated reason. I'd like to have some way to tell known-bad compilers, so that we know to avoid them..
