+ BASH PATCH REPORT
+ =================
+
+Bash-Release: 3.0
+Patch-ID: bash30-001
+
+Bug-Reported-by: Karlheinz Nolte <kn@k-nolte.de>
+Bug-Reference-ID: <20040801200058.GA3311@mars.home.k-nolte.de>
+Bug-Reference-URL: http://lists.gnu.org/archive/html/bug-bash/2004-08/msg00009.html
+
+Bug-Description:
+
+ The following script triggers the segfault.
+ This was found by Costa Tsaousis the author of FireHOL.
+ He wrotes:
+
+ "I think I have found the bug. The script bellow crashes at the
+ third echo (UNSET). It seems to be a problem of the "unset" BASH
+ function when erasing arrays. It leaves something behind so that if
+ the array just unset is referenced, it produces a segmentation fault.
+ According to the documentation the first and the third expansions
+ should be exactly the same."
+
