How did you try it? `std::cout << array->ToString() << std::endl;` creates a temporary `std::string`. So I think that you can't touch the `std::string` in `Float64Array::Print`. (I think that you can't refer the `std::string` without specifying its address explicitly.) > We have been experimenting with instrumenting the code using [`AddressSanitizer`](https://github.com/google/sanitizers/wiki/AddressSanitizer) to determine the root cause of the apparent memory corruption. Could you share the log from `AddressSanitizer`? > In order to unblock this pull request, it may make sense to treat this as an independent issue. I agree with you. > We apologize for the delay on getting to the root cause of this issue. No problem! Thanks for working on this! -- This is an automated message from the Apache Git Service.
