print0x000a and print0x000c call std::stoul(value.toString()), but the stored type of Canon tags 0x000a and 0x000c is not enforced during parsing, so a crafted makernote can hand them a non-numeric ASCII value. stoul then throws std::invalid_argument, which Exifdatum::write does not catch (it only guards std::out_of_range), so it escapes during -pa printing. Catch both and fall back to the raw value, like the existing path in print0x000c.
