Are you sure you didn't run out of memory? Check dmesg for OOM-killer.
You're right, the OOM killer came along and killed the compiler. I found this a bit surprising, since llvm itself was compiled fine, and I'd expect clang to be smaller than llvm. In any case, may be time for checkreqs? Here's the output of `free` from that machine: djc@enrai clang $ free total used free shared buff/cache available Mem: 7972852 592244 7167088 23212 213520 7314916 Swap: 524284 512232 12052
clang has a few big files (*Sema*), and sadly they come near one another. Check-reqs can't help with this. It's practically impossible to calculate proper memory use since it depends on arch, compiler (e.g. gcc6 uses more memory than gcc5), job count, distcc use... plus, there's swap to consider. Last time someone tried that, chromium claimed I need 30G RAM or so.
