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'):
