			     =================

Bash-Release:	4.3
Patch-ID:	bash43-036

Bug-Reported-by:	emanuelczirai@cryptolab.net
Bug-Reference-ID:	<f962e4f556da5ebfadaf7afe9c78a8cb@cryptolab.net>
Bug-Reference-URL:	http://lists.gnu.org/archive/html/bug-bash/2015-02/msg00071.html

Bug-Description:

When evaluating and setting integer variables, and the assignment fails to
create a variable (for example, when performing an operation on an array
variable with an invalid subscript), bash attempts to dereference a null
pointer, causing a segmentation violation.

Patch (apply with `patch -p0'):
