+			     BASH PATCH REPORT
+			     =================
+
+Bash-Release:	4.2
+Patch-ID:	bash42-010
+
+Bug-Reported-by:	Mike Frysinger <vapier@gentoo.org>
+Bug-Reference-ID:	<201104122356.20160.vapier@gentoo.org>
+Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2011-04/msg00058.html
+
+Bug-Description:
+
+Bash did not correctly print/reproduce here documents attached to commands
+inside compound commands such as arithmetic for loops and user-specified
+subshells.  This affected the execution of such commands inside a shell
+function when the function definition is saved and later restored using
+`.' or `eval'.
