Hi,
I'm having difficulties compiling the fastcomp backend with gcc4.6 in a VM
running Linux. Maybe somebody had the same problem before I'm digging
deeper. I'm following the build instructions here
(https://github.com/kripken/emscripten/wiki/LLVM-Backend), and on OSX with
Xcode's clang this worked fine. I'm now trying to get this to compile in a
VM running 64-bit Ubuntu 12.04 and gcc4.6.
Configuring works fine, compiling with 'make -j2' starts normal until at
some point:

Ran "bash" "/tmp/chef-script20140310-4298-13631kl" returned 2
Anyone else had the same problem and figured out a workaround? First thing
I'll try is to try a different GCC version (older or newer), and if nothing
try compiling with a vanilla clang.
Cheers,
-Floh.
