This is also <http://bugs.debian.org/522099>, and as discussed there,
it seems to be a misunderstanding about the needed arguments for
PERL_SYS_INIT3(). The test case calls the macro (twice) with the
perl_parse() arguments, but apparently the "real" main() argc, argv and
env are the right ones.

If this is correct, maybe the attached documentation patch would help
to avoid similar confusion in the future?
