* Exception handling in destructors: print an error message, then

* If you're not in a destructor, you usually want to use `ignoreExceptionExceptInterrupt()`.
*
* This function might also be used in callbacks whose caller may not handle exceptions,
* but ideally we propagate the exception using an exception_ptr in such cases.
* See e.g. `PackBuilderContext`
