 valgrind: m_mallocfree.c:304 (get_bszB_as_is): Assertion 'bszB_lo ==
 bszB_hi' failed.
 valgrind: Heap block lo/hi size mismatch: lo = 353400, hi = 0.
 This is probably caused by your program erroneously writing past the
 end of a heap block and corrupting heap metadata.  If you fix any
 invalid writes reported by Memcheck, this assertion failure will
 probably go away.  Please try that before reporting this as a bug.

 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.
