Comment:

 Works for me:

 {{{
         Tue Nov 27 13:32 2007 Time and Allocation Profiling Report
 (Final)

            a.out +RTS -P -RTS MMDataA

         total time  =        6.50 secs   (325 ticks @ 20 ms)
         total alloc = 4,296,710,936 bytes  (excludes profiling overheads)
 }}}

 I wonder if this is some incompatibility with whatever kernel version you
 have?  GHC is using `timer_create()`, a relatively new API.

 Which version of Linux are you running, and where did you get your GHC
 binary from?
