--- Comment #5 from Adam Martinson amartinson@codeweavers.com 2011-06-09 10:34:09 CDT --- Setting wininet_zalloc() to use heap_alloc_zero() instead of heap_alloc() fixes the uninitialized value in inflateReset2(), but doesn't change anything otherwise, so that part is probably just a harmless bug in zlib.
