The problem is that by default VS2017 builds Clang in parallel to how many cores you have <br></div><div class="gmail_default" style="font-family:courier new,monospace;font-size:small;color:#000000"><br></div></div><div dir="ltr"><div class="gmail_default" style="font-family:courier new,monospace;font-size:small;color:#000000">That would explain my problem in building clang then as I have an eight core Ryzen 7 1700X with only 8GB of RAM.

How much physical memory your system has is totally irrelevant, you still cannot "run out of memory" from the process's point of view unless you also run out of disk space for swap, which is extremely unlikely unless you have configured a very small swap. </div></div></div>
