+			     BASH PATCH REPORT
+			     =================
+
+Bash-Release:	4.3
+Patch-ID:	bash43-029
+
+Bug-Reported-by:	Michal Zalewski <lcamtuf@coredump.cx>

+
+Bug-Description:
+
+When bash is parsing a function definition that contains a here-document
+delimited by end-of-file (or end-of-string), it leaves the closing delimiter
+uninitialized.  This can result in an invalid memory access when the parsed
+function is later copied.
+
+Patch (apply with `patch -p0'):
