+			     BASH PATCH REPORT

+
+Bash-Release:	4.2
+Patch-ID:	bash42-024
+
+Bug-Reported-by:	Jim Avera <james_avera@yahoo.com>
+Bug-Reference-ID:	<4F29E07A.80405@yahoo.com>

+
+Bug-Description:
+
+When `printf -v' is used to set an array element, the format string contains
+`%b', and the corresponding argument is the empty string, the buffer used
+to store the value to be assigned can be NULL, which results in NUL being
+assigned to the array element.  This causes a seg fault when it's used later.
