I'll include log of our discussion on #yocto from yesterday:

20:56 < JaMa> khem: those gcc build issues are always about different constant or invalid file (expected } or something) so as I said before I believe it's some sort of race condition with parallel build in gcc or with parallel build of all those *gcc* recipes, but hard to reproduce because with second run it's usually gone
20:57 < khem> hmmm
20:57 < khem> JaMa: so the build fails saying what ?
20:57 < khem> first time
20:58 < JaMa> thanks to RP's fix I can at least rebuilt just the one which was failing instead of all *gcc* again
20:58 < JaMa> undeclared constant or expected } or something, I think each time the error is a bit different
20:58 < khem> JaMa: I have changed gcc-4.7 to avoid some overlappings which should help too
20:59 < khem> oh I see
20:59 < khem> that means a .h file is not generated yet and is being referenced or included
20:59 < khem> and you said its looking in srcdir ?
21:00 < JaMa> last time we talked about it, I've blamed do_headerfix because it was running in parallel with do_compile in some other *gcc* recipe
...
21:32 < JaMa> khem: I've found couple of old build logs with gcc failing http://build.shr-project.org/tests/jama/gcc-upgrade-issue/
