Hmmm ... this is interesting, but unfortunately backtraces from
non-debug builds are often not very trustworthy, and that seems to have
happened here. CreateCopyDestReceiver doesn't call pg_mb2wchar, and
pg_mb2wchar doesn't call MemoryContextAlloc, so we're being lied to
right at the spot where we might've hoped to learn something.
Could you please rebuild the executables with --enable-debug and try
again?
regards, tom lane
