[Bug libc/955] New: Segmentation fault while converting with iconv and IBM939

["grhoten at jtcsv dot com" <sourceware-bugzilla at sources dot redhat dot com>]

While using iconv to convert the character \uFFFF {0xef, 0xbf, 0xbf} iconv core
dumps.  iconv can convert all the other valid UTF-8 characters between \u0000
and \uFFFE without core dumping.  I know that some Unicode characters aren't
representable in IBM939, but it shouldn't fail with a segmentation fault. Other
iconv converters don't fail when \uFFFF is converted.


Here is a stack trace.
#0  0x0000002a96404be4 in gconv () from /usr/lib64/gconv/IBM939.so
#1  0x00000035d0121edb in __gconv_transform_utf8_internal ()
   from /lib64/tls/libc.so.6
#2  0x00000035d011d558 in __gconv () from /lib64/tls/libc.so.6
#3  0x00000035d011cbbb in iconv () from /lib64/tls/libc.so.6

I'm using Fedora Core 3 on AMD64.
