* You can pass them a format message and arguments, just as if it where a printf.
* It is converted to a XBT_CRITICAL logging request.
- * Be careful: the boolean expression that you want to test should not have side effects, because assertions are
- * disabled at compile time if NDEBUG is set.
+ * An execution backtrace is also displayed, unless the option --log=no_loc is given at run-time.
+ *
+ * Unlike the standard assert, xbt_assert is never disabled, even if the macro NDEBUG is defined at compile time. So
+ * it's safe to have a condition with side effects.
+ *
+ * In model-checking mode, a failed xbt_assert() is reported as a failed MC_assert().
