[bug-gnu-libiconv] RE: [rt.cpan.org #28850] Korean hanging CRITICAL

[Letellier, Aldo]

Thanks for your reply, I know about the Sun's Iconv limitations
so I work around that by doing a the following:
 EUC-KR => UTF-8 => ISO-2022-KR

Works, but it CORE DUMPS, see gdb log
I'm going to do the same trace using GNU libiconv

Yes, I know.  The point was to see whether it works at all.  I've now
been able to try it myself on Solaris and I've seen the same behavior.

However, I've also tried Text::Iconv with GNU libiconv on NetBSD, and
your test program works fine there.

So, it seems that the problem only occurs on Solaris.  I'm not yet sure
where to start debugging.
