Hi!

----

[CC:'ing Werner since this is i18n related and was only observed on
SuSE 12.3 Linux for now...]

Attached (as "astksh20130409_suse123_32bit_builtin_iconv_hang1.txt.gz")
is a (compressed) text file which causes the AST "iconv" builtin
utility from ast-ksh.2013-04-09 to "hang" in an endless loop in 32bit
i386 builds (AMD64 64bit builds are OK... *ONLY* the 32bit builds loop
forever...).

Example:
-- snip --
$ gunzip  astksh20130409_suse123_32bit_builtin_iconv_hang1.txt.gz
$ LC_ALL=en_US.UTF-8 ../build_i386_32bit_debug/arch/linux.i386/bin/ksh
-c 'builtin iconv ; iconv -f UTF-8
/tmp/astksh20130409_suse123_32bit_builtin_iconv_hang1.txt >/tmp/zzz2 ;
true'
<hangs forever>
-- snip --

Neither 32bit or 64bit builds trigger any valgrind hits and the gdb
stacktrace is no very usefull either:
-- snip --
$ LC_ALL=en_US.UTF-8 gdb --args
../build_i386_32bit_debug/arch/linux.i386/bin/ksh -c 'builtin iconv ;
iconv -f UTF-8 /tmp/astksh20130409_suse123_32bit_builtin_iconv_hang1.txt
>/tmp/zzz2 ; true'
