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.
