[cfe-dev] Out of Memory Building Clang and LLVM

[nick via cfe-dev]

Greetings, 

Seems I'm running out of memory on a host system trying to build llvm, tooling and clang. It was configured
as:
cmake -DLLVM_ENABLE_PROJECTS=clang -G "Unix Makefiles" ../llvm

and build with:

make -j4 using gcc as the host compiler, version 8.

The dmesg I'm getting is related to the linker and not sure if the linker has a bug or it's normal
to expect 3GB or more used for linking clang. Doesn't seem to be but not sure.

dmesg output:
[186517.023397] Out of memory: Kill process 2143 (ld) score 286 or sacrifice child
[186517.023403] Killed process 2143 (ld) total-vm:4622188kB, anon-rss:3202188kB, file-rss:4kB, shmem-rss:0kB
