Bash Version: 3.1
Patch Level: 0
Release Status: release

Description:
        A refference to a shell variable doesn't work under specific case.
        The result of the following operations isn't shown and prompt doesn't
        return when environment variable LANG is Ja_JP on AIX 5.2L
        $ i=123456789012l
        $ echo ${i%l}
        (Pronput doesn't return...)

Fix:
        This problem is avoidable by the modification shown below:
        Replace l. 3365 in subst.c ("ret = wcsdup (wparam);")
        to the following two lines:

            ret = (wchar_t *) malloc((size_t)(n + 1) * sizeof(wchar_t));
            wcscpy(ret, wparam);
</output>
