Hi!
----
The following testcase hangs ast-ksh.2013-09-04 in the zh_CN.GB18030
locale in a busy-loop (with and without my patches) ... but only on
Illumos/AMD64/64bit:
-- snip --
typeset -r utf8_euro_char2=$'\342\202\254'
(( ${#utf8_euro_char2} ))
-- snip --
$ bash -c 'LC_ALL=zh_CN.GB18030 ~/bin/ksh x.sh' # ...
... hang...
I have no clue why... ;-(
Sample stack trace looks like this:
-- snip --
dbx: warning: Interrupt ignored but forwarded to child.

2666 else while(mbchar(str))

-- snip --
I guess somehow the code doesn't react good to the detail that
$'\342\202\254' isn't a valid character sequence in the GB18030
multibyte encoding... ;-(
-- snip --
$ cat x.sh
builtin wc
printf '\342\202\254' | wc -m -X
$ bash -c 'LC_ALL=zh_CN.GB18030 ./arch/sol11.i386\-64/bin/ksh x.sh'
wc: warning: 0xac: invalid multibyte character byte
