Hi!
----
While digging through test logs for a Solaris 11/x86/32bit debug build
I found this core dump caused by ast-ksh.2012-05-18's "shcomp"
crashing compiling "namespace.sh" (locale was "zh_CN.GB18030" but I
see a similar core dump for the "C" locale):
-- snip --
$ dbx - /var/core/core.uid1000.gid100.pid11407.shcomp

To remove this message, put `dbxenv suppress_startup_message 7.6' in your .dbxrc

Stack trace sounds familiar... is this a known problem ?
