I am getting the following compilation error for prog_tests/uprobe_autoattach.c

mem variable is now used in one of the asserts so it shouldn't be freed right away. Move free(mem) after the assert block.
Looks good, but I rephrased this a bit to avoid confusion. It's false positive given we only compare the addresses but don't deref mem, which the compiler might not be able to follow in this case.

Right. Thank you for fixing up the commit message.
