+
+The new nameref assignment functionality introduced in bash-4.3 did not perform
+enough validation on the variable value and would create variables with
+invalid names.

+Bug-Description:
+
+When bash is running in Posix mode, it allows signals -- including SIGCHLD --
+to interrupt the `wait' builtin, as Posix requires.  However, the interrupt
+causes bash to not run a SIGCHLD trap for all exited children.  This patch
+fixes the issue and restores the documented behavior in Posix mode.

+Bug-Description:
+
+Bash does not clean up the terminal state in all cases where bash or
+readline  modifies it and bash is subsequently terminated by a fatal signal.
+This happens when the `read' builtin modifies the terminal settings, both
+when readline is active and when it is not.  It occurs most often when a script
+installs a trap that exits on a signal without re-sending the signal to itself.
+
+Patch (apply with `patch -p0'):
