When I profiled your code previously, it worked fine on either a
Linux/x86 or Solaris/sparc machine (I don't remember which), but not on
MacOS/powerpc, so yes it does look like a platform-specific problem.
Strangely, although the profile was generated OK on the other platform,
the hp2graph tool for converting it to a graph seg faulted there, but
worked correctly on MacOS/powerpc.
