Heap profiling dumped NULs

Hi,

I can't reproduce it, but on one occasion running profiling with -hd,
I got corrupt .hp output, with a large block of NULs in an otherwise
normal output (The output is large, but I can make it available if
anybody wants it).  Rerunning the exact same command line produced a
normal .hp.

Just in case you'd like to know.
