Doesn't like the void* casts, e.g. here:

		c.data_count += sizeof(data) // sizeof(data[0])
		c.data = <float*>realloc(c.data, c.data_count * sizeof(data[0]))
		memcpy(<char*>c.data + c.data_count * sizeof(data[0]) - sizeof(data), data, sizeof(data))

		cdef uint32_t[6] indices = [0, 1, 2, 0, 2, 3]

		for i in range(6):
			indices[i] += c.index_count // 6 * 4

		c.index_count += sizeof(indices) // sizeof(indices[0])
		c.indices = <uint32_t*>realloc(c.indices, c.index_count * sizeof(indices[0]))
		memcpy(<char*>c.indices + c.index_count * sizeof(indices[0]) - sizeof(indices), indices, sizeof(indices))

Should cast to char* instead.
