Comment (by simonmar):

 The SIGALRMs are normal, that's just GHC's interval timer (we shouldn't
 really be using SIGALRM, but that's another issue).

 It seems that GHC is just allocating all the memory, and I don't know why.
 It's odd that changing CFLAGS makes a difference: we don't actually use
 CFLAGS in our build system, so I have no idea what effect setting it has.

 The next step for debugging is to compile GHC with debugging support, and
 generate some debugging logs.  In your build tree:

 {{{
 $ cd ghc/compiler
 $ rm stage2/ghc-*
 $ make stage=2 EXTRA_HC_OPTS=-debug
 $ ./stage2/ghc-inplace --interactive +RTS -Ds -Sstderr 2>&1 | tee log
 }}}

 and send/attach the log file.  (you should be able to attach files using
 the "Attach File" button above).
