When the tensor type is not an integral type, the operation writes to that memory area and crashes the Python interpreter. Once the file holds enough bytes for the tensor, the snippet causes a segmentation fault, because the allocator does not override the virtual method needed to be marked as returning an opaque handle.","solution":"This is fixed in versions 1.15.5, 2.0.4, 2.1.3, 2.2.2, 2.3.2, and
