+Note: see also the FAQ in the source distribution.
+It contains workarounds to several common problems.
+In particular, if Valgrind aborted or crashed after
+identifying problems in your program, there's a good chance
+that fixing those problems will prevent Valgrind aborting or
+crashing, especially if it happened in m_mallocfree.c.
+
+If that doesn't help, please report this bug to: www.valgrind.org
+
+In the bug report, send all the above text, the valgrind
+version, and what OS and version you are using. Thanks.
