Hi,

To me it looks like the job is trying to build LLVM and Clang in '-O0
-g' mode, and the machine does not have enough RAM per core to run the
linker.  (The machine has plenty of RAM in general, but it also has
many cores.)

Could we switch the job to build in Release+Assert?

Yes, that's the right repository.  Please feel free to add more
(reasonably-sized) jobs to my buildbot.  It would be best if the
libomp and OMPT jobs did not try to build the compiler like they try
to do now.  That would leave more time for other jobs.
