I have posted a comment to that blog.  For the archive, here's what it says:

Starting with OCaml 4.00.0, there is an easy way to activate the debug version of the runtime:

1. configure OCaml with "-with-debug-runtime"
2. compile and install OCaml
3. compile your program with "-runtime-variant d"

This will compile your program with a version of the runtime which has assertions all over the place, and does a thorough check of the heap structure at each major GC (and at each compaction). If you then follow Rich’s advice, you should be able to narrow down the source of the heap corruption quite easily.
