IMHO you may use the --args option of the gdb. Be sure that all
debugging symbols are installed (libc e.g.) and ksh is not stripped.
Then start your ksh with
gdb --args ksh
... set a break point as usual
break iconv
run
... wait on ksh
builtin iconv
iconv -t UTF-8 astksh20130409_suse123_32bit_builtin_iconv_hang1.txt
now this should trigger the breka and with the help of `bt' the place where
iconv is used the first time should be visible.
