 			     BASH PATCH REPORT
			     =================
 
Bash-Release: 3.2
Patch-ID: bash32-019
 
Bug-Reported-by:	Thomas Loeber <ifp@loeber1.de>
Bug-Reference-ID:	<200703082223.08919.ifp@loeber1.de>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2007-03/msg00036.html
 
Bug-Description:
 
When rl_read_key returns -1, indicating that bash's controlling terminal
has been invalidated for some reason (e.g., receiving a SIGHUP), the error
status was not reported correctly to the caller.  This could cause input
loops.
