==25665== More than 10000000 total errors detected.  I'm not reporting any more.
==25665== Final error counts will be inaccurate.  Go fix your program!
==25665== Rerun with --error-limit=no to disable this cutoff.  Note
==25665== that errors may occur in your program without prior warning from
==25665== Valgrind, because errors are no longer being displayed.
==25665== 

valgrind: m_mallocfree.c:288 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo = 162496, hi = 1099511790272.
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.
