+                            BASH PATCH REPORT
+                            =================
+
+Bash-Release: 3.2
+Patch-ID: bash32-018
+
+Bug-Reported-by:       osicka@post.cz
+Bug-Reference-ID:      <228.177-19682-1132061412-1179356692@post.cz>
+Bug-Reference-URL:     http://lists.gnu.org/archive/html/bug-bash/2007-05/msg00061.html
+
+Bug-Description:
+
+In certain cases, bash can lose the saved status of a background job, though
+it should still be reported by `wait'.  Bash can also loop infinitely after
+creating and waiting for 4096 jobs.
+
