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

Bash-Release: 2.05b
Patch-ID: bash205b-012

Bug-Reported-by:        Michal Zalewski <address@hidden>
Bug-Reference-ID:
Bug-Reference-URL:

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:
