We're on RHEL 7, compiling with clang 8.

build:

  /proj/flexasic/app/ninja/1.8.2/SLED11-64/bin/ninja -j8 -C llvm/build-all-builtins  all

It works almost all of the time, but every now and then I get that error. And if try to reproduce it it works, so I suspect it's related to having bad luck when running many tests in parallel so there is some kind of conflict with the temporary files.
