Try to answer the following questions:
- what's the difference between BOOST_DISABLE_ASSERTS and NDEBUG?
- does defining BOOST_ENABLE_ASSERT_HANDLER affect whether assertions
are enabled or not?
- what's the difference between BOOST_ASSERT and BOOST_ASSERT_MSG
The answers one would expect are:
- BOOST_DISABLE_ASSERTS disables all assertions done with Boost.Assert,
while NDEBUG disables all assertions done with Boost.Assert or standard
- No, defining a handler is orthogonal to whether assertions are enabled
- The only difference is that _MSG allows to define a message.
Unfortunately, none of those answers are true: defining NDEBUG does not
disable BOOST_ASSERT (but it does disable BOOST_ASSERT_MSG -- nice
inconsistency) if BOOST_ENABLE_ASSERT_HANDLER is set.
