Bug#274390: memory leak in iconv_open/iconv_close

[Atsushi Nemoto <anemo@mba.ocn.ne.jp>]

Package: libc6
Version: 2.3.2.ds1-16

Just iconv_open and iconv_close for some encodings (UTF-16,
ISO-2022-JP, etc.) causes memory leak.

This is a test code.

#include <iconv.h>
int main(int argc, char** argv)
{
	while(1) {
		iconv_close(iconv_open("UTF-16LE", "UTF-16LE"));
	}
	return 0;
}

Perhaps this is because gconv_end in the encoding module never called.
It seems this bug has been fixed in upstream.  I suppose this patch
fixes the problem.
