+                            BASH PATCH REPORT
+                            =================
+
+Bash-Release: 3.2
+Patch-ID: bash32-038
+
+Bug-Reported-by:       Wojciech Puchar <wojtek@wojtek.tensor.gdynia.pl>
+Bug-Reference-ID:      <200803131141.m2DBf9vo001136@wojtek.tensor.gdynia.pl>
+Bug-Reference-URL:     http://lists.gnu.org/archive/html/bug-bash/2008-03/msg00029.html
+
+Bug-Description:
+
+When reading input lines into a single variable using the `read' builtin,
+bash did not free the memory it read after assigining it to the named
+variable, causing a memory leak noticable when reading large amounts of
+data.
+
+
