This indicates that somebody is pfree'ing a pointer that did not come
from palloc, or possibly pfree'ing the same pointer twice. It could be
that the bad pfree is the indirect result of an earlier memory clobber,
too.
Given that you are using user-defined C functions it seems highly likely
that the bug is in your code and not Postgres. If you can reproduce the
bug without any of your own C functions having been executed, please
send along a script that does it ...
