Several static analyzers (clang's one, Facebook Infer, etc.) warn about NULL pointer dereferences after a call to CU_ASSERT_PTR_NOT_NULL_FATAL() in the test code written using CUnit framework. This is because this CUnit macro is too complex for them to understand that the pointer cannot be NULL: it is translated to a call to CU_assertImplementation() with an argument as TRUE in order to mean that the call is fatal if the asserted condition failed (cf. http://cunit.sourceforge.net/doxdocs/group__Framework.html). A possible solution could consist in replacing the CU_ASSERT_..._FATAL() calls by assert() ones, as most static analyzers know about assert(). Nevertheless this seems to go against CUnit's API. An alternative solution consists in overriding CU_ASSERT_..._FATAL() macros in order to expand to assert() after a call to the matching CU_ASSERT_...() non-fatal macro. This appears to work fine and to remove many false-positive warnings from various static analyzers. As this substitution should only occur when using static analyzer, put it under #ifdef __CHECKER__, which is the macro used by sparse when analyzing the Linux kernel.
