BASH PATCH REPORT
=================
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.
