assert(blah blah) in the C code base
Greetings! I'm working on Issue19995, and I'm seeing stuff like this: assert(PyLong_Check(val)); My question is: Are these asserts in final production code? My possible scenarios are: - the assert isn't in place - the assert isn't working correctly - PyLong_Check isn't working correctly - the non-ints are being converted before the function containing the assert is called The fourth possibility is the most likely, but since I don't know how assert() works in C I can't be sure. Any quick pointers? -- ~Ethan~

http://www.cplusplus.com/reference/cassert/assert/ They should be completely removed in a non-debug build (when NDEBUG is defined). Eric.
Yes, looks like NDEBUG is not defined only when you run
./configure --with-pydebug
if test "$Py_DEBUG" = 'true'; then
:
else
OPT="-DNDEBUG $OPT"

They are compiled in when --with-pydebug is passed to configure. They should "never" fail. -- Regards, Benjamin
