I just committed a fix for this to the trunk (r9781).

I didn't use your patch, although I used the same basic approach.  The two main
differences were:

- I used an OSet instead of a VgHashTable.  OSet's interface was sufficiently
  generic that I didn't have to modify it at all.

- I didn't compute hashes of ExeContexts.  This means that there is no danger
of
  two different ExeContexts unluckily having the same hash value and thus being
  erroneously merged.

I also made the change to VG_(HT_to_array) that you identified.

Thanks for all your work towards fixing this bug.
