This PR replaces the potentially unsafe
memset(this, 0, offsetof(BitStream, allocator))call within theBitStream(IMemAlloc *a)default constructor with a standard C++ member initializer list.Original
memsetapproach is fragile and could lead to memory corruption if the class layout or padding changes in the future, zeroing out theallocatormember itself before assignment.
