Has anyone tried building the backend with a debugging malloc library?
dbmalloc, or Electric Fence, or Purify would probably help smoke out
any remaining coding errors of this kind (using already-freed space,
writing past the end of a malloc'd block, etc).
Purify is a commercial product, but the other two are freeware and
shouldn't be hard to find on the net.
