 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.
