valgrind: m_mallocfree.c:268 (mk_plain_bszB): Assertion 'bszB != 0' failed | AND | valgrind: m_mallocfree.c:294 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed. | AFTER various Bitmap Valgrind errors

[Roel Van de Paar]

valgrind: m_mallocfree.c:294 (get_bszB_as_is): Assertion 'bszB_lo == bszB_hi' failed.
valgrind: Heap block lo/hi size mismatch: lo = 98, 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.

And (another trial):

valgrind: m_mallocfree.c:268 (mk_plain_bszB): Assertion 'bszB != 0' failed.
valgrind: 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.

And this after various other bitmap related (inc one strncpy) Valgrind messages. Full error logs attached for review.

The first Valgrind error (conditional jump is ... ) is bug 1182793.

The next ones must be either bug 1179974 exactly, either should be fixed together anyway. Closing this one as duplicate and raising bug 1179974 priority.
