andishgar opened a new issue, #48339: URL: https://github.com/apache/arrow/issues/48339
### Describe the enhancement requested Currently, the functions in `util/ubsan.h` require a type that is trivially copyable. However, before performing its intended operation, it calls the default constructor of the type, as shown in the code below: [[link](https://github.com/apache/arrow/blob/b2e8f2505ba3eafe65a78ece6ae87fa7d0c1c133/cpp/src/arrow/util/ubsan.h#L56-L61)](https://github.com/apache/arrow/blob/b2e8f2505ba3eafe65a78ece6ae87fa7d0c1c133/cpp/src/arrow/util/ubsan.h#L56-L61) It is possible, however, for a type to be trivially copyable without having a default constructor, for example: ```c++ struct A { A(int a) : a(a) {} int a; }; ``` ### Component(s) C++ -- This is an automated message from the Apache Git Service.
