+ BASH PATCH REPORT
+ =================
+
+Bash-Release: 4.3
+Patch-ID: bash43-029

+
+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.
