			     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'):
