Hmm ... I can reproduce the problem on Fedora 11. Given a UTF8-encoded
database (I don't think locale matters), 8.3.7 works as described, but
8.3.8 fails as described, as do 8.4.1 and HEAD. Given that the only
difference in plperl.c between 8.3.7 and 8.3.8 is the addition of the
PERL_SYS_INIT3 call, I have to suppose that that's screwing up
Text::Iconv somehow.
I'd bet a small amount of money that this is somehow related to the
UTF8-specific code in plperl_safe_init(), which always struck me
as unexplained hocus-pocus. Since the test function is plperlu,
plperl_safe_init() obviously can't be directly to blame; but I'm
thinking that what it's really doing is papering over some missed
initialization issue that affects plperlu functions too.
