testnullpointer.cpp: Add test for dereferencing returned NULL pointer ( #2401 )
...
This adds a regression test to make sure that directly dereferencing a
returned NULL pointer issues a warning.
This has been asked on Stack Overflow:
https://stackoverflow.com/q/58981369
Cppcheck 1.89 does not warn for such a code, but 1.90 dev does. So it
is a good idea to make sure it is detected in the future too I guess.
