We need more information first before saying "bad hardware" -- in
particular, was the machine overtaxed, were the input files proper,
I'm asking because clang has a number of bugs in bugzilla where the
host ran out of memory trying to compile things and clang didn't fail
gracefully when allocating memory, handling inputs, etc.
