Antoine Pitrou commented on ARROW-16876:
----------------------------------------
1) For the record, is there a particular reason for compiling without RTTI?
2) What does dynamic_cast do if RTTI is disabled?
> NDEBUG required by -fno-rtti
> ----------------------------
>
> Key: ARROW-16876
> URL: https://issues.apache.org/jira/browse/ARROW-16876
> Project: Apache Arrow
> Issue Type: Wish
> Components: C++
> Affects Versions: 8.0.0
> Reporter: Jefferson Carpenter
> Priority: Minor
>
> Some of the code in checked_cast.h uses {{dynamic_cast}} unless NDEBUG is
> defined. Defining NDEBUG affects other C++ functionality, for example it
> causes {{assert}} statements to be compiled out of the program.
> It would be nice if Arrow provided some mechanism for compiling without RTTI
> (viz. not using dynamic_cast) without requiring NDEBUG to be defined and
> affecting assertions in other code.
>
> P.S. An alternative workaround would be to include Arrow headers through a
> project header that defines NDEBUG, has the Arrow include statements, and
> then undefines NDEBUG.
