64 bit PostgreSQL 8.3.6 build on AIX 5300-09-02-0849 with IBM XL C/C++ 10.1.0.1 - initdb fails (could not dump unrecognized node type: 650)

Make builds fine, but pg_regress: initdb fails. src/test/regress/log reads:

Running in noclean mode. Mistakes will not be cleaned up.
The files belonging to this database system will be owned by user "cmihai".
This user must also own the server process.

The database cluster will be initialized with locale C.
The default database encoding has accordingly been set to SQL_ASCII.
The default text search configuration will be set to "english".

initdb: 64-bit XCOFF executable or object module not stripped

All commands seem to be work in so far as they don't have missing modules
(ldd) and run. Not much else I can test without a initdb though.

I have found my issue to be similar to
http://archives.postgresql.org/pgsql-ports/2005-06/msg00002.php(unresolved).

Any suggestions / additional tests I can run to pinpoint the problem?

If I use IBM Debugger of AIX, I get right before the crash:

creating system views ...
exec() -> sh
exec() -> postgres
Execution terminated.

So it happens somewhere in postgres code.
