I can confirm this with llvm 3.3-r1 and gcc 4.8.1 on 32 bit system.
llvm-3.3-r1 successfully emerges with when compiled with gcc-4.6.3 or gcc-4.7.3 on ppc. + + static-analyzer : Install the Clang static analyzer (requires USE=clang) The clang USE flag is not required for successful emerging with those versions. Disabling libffi and static-analyzer does not prevent the error under gcc-4.8.1.
I can confirm that this bug still reproducible while building sys-devel/llvm-3.3-r1 on: Portage 2.2.7 (default/linux/amd64/13.0/desktop, gcc-4.8.2, glibc-2.17, 3.5.4-gentoo x86_64).
This is result of functions inlining - usual problems, escalating from GCC 4.6 to 4.7 to 4.8. In this case there are "-finline-functions-called-once" (by -Os). Workarounds (amd64): is-flag -Os && append-flags -fno-inline-functions-called-once or is-flag -Os && append-flags -finline-small-functions or upgrade inlining from -Os to -O2 (IMHO best): is-flag -Os && append-flags -finline-small-functions -findirect-inlining Or, common way - to find affected (bad inlined) function and make them "noinline". PS My own 4.8 global stabilization flags addon (to -Os/-O2/-O3/-Ofast): -finline-small-functions -findirect-inlining -fno-graphite-identity -fno-inline-functions and optional: -fno-ipa-cp-clone (may be omitted with special care about few packets)
Cleaning old llvm/clang bugs. Newer versions (tested with 3.7.0 but I think 3.6.0 was ok too) compile fine with -Os and gcc-4.8, so marking this one as fixed!
