At the risk of sounding like a broken record, could you please file a
report on our bug tracker:
http://caml.inria.fr/mantis/
It's the best way to ensure that the issue will not slip past our radar.

Also, please tell us which versions of MacOS X and of Xcode you're using.

Because this sounds very much like a bug in the C library or in the
linker: the "environ" variable is standardized as part of POSIX and
derived standard like the Single Unix Specification, and MacOS X has
been very very good so far at following POSIX standards.
