If I'm reading things correctly, https://github.com/regehr/itc-benchmarks/blob/master/01.w_Defects/free_null_pointer.c is a test that a verifier complains about a free of a NULL pointer.

However, it's legal to call free on a NULL pointer;
to quote "7.20.3.2 The free function" of http://www.open-std.org/JTC1/SC22/wg14/www/docs/n1124.pdf

If ptr is a null pointer, no action occurs

If so, are these tests requiring false positives? (or am I misunderstanding things?)

Hope this is constructive
