Hmm, another occurrence of the elusive GC bug.  I can't repeat this one
either.

Can you check that it is repeatable for you:

  $ cd libraries/base
  $ rm GHC/PArr.o
  $ make GHC/PArr.o

and let me know whether you get the same crash repeatedly.  Could you
also try this:

  $ rm GHC/PArr.o
  $ make GHC/PArr.o EXTRA_HC_OPTS="+RTS -C0 -RTS"

which might help to make it more repeatable (that disables the context
switch timer).

Cheers,
