Assertions in header files slows down an interpreter, so they should be turned off by default (simple `make`). To enable them, define a macro `RUBY_DEBUG=1` (e.g. `make cppflags=-DRUBY_DEBUG` or use `#define` at the very beggining of the file. Note that even if `NDEBUG=1` is defined, `RUBY_DEBUG=1` enables all assertions. [Feature #16837] related: https://github.com/ruby/ruby/pull/3120 `assert()` lines in MRI *.c is not disabled even if `RUBY_DEBUG=0` and it can be disabled with `NDEBUG=1`. So please consider to use `RUBY_ASSERT()` if you want to disable them when `RUBY_DEBUG=0`.
