BASH PATCH REPORT
=================
Bash-Release: 3.0
Patch-ID: bash30-021

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.
