[jira] [Created] (ARROW-16876) NDEBUG required by -fno-rtti

Jefferson Carpenter created ARROW-16876:
-------------------------------------------

             Summary: 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


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.
