i've got an ubuntu 14.10 x64 VM with 4GB of RAM(3GBs free for compile)
  - before your post ~2GBs - more RAM is currenlty not possible
that amount of RAM let me compile more then before but still stops with ld terminated with signal 9

what amount of RAM is currently needed for building clang head? it wasn't that much before

not with gcc4.9.1 but it seems with gcc4.9.2 (https://launchpad.net/~ubuntu-toolchain-r/+archive/ubuntu/ppa/+build/6539169)
i will retest if i get more RAM for my tests
