			     BASH PATCH REPORT
			     =================

Bash-Release:	4.2
Patch-ID:	bash42-052

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'):
