executor: prevent non-null expected warnings The added test triggers warnings like these: <stdin>: In function ‘syz_mount_image.constprop’: <stdin>:298:3: error: argument 1 null where non-null expected [-Werror=nonnull] In file included from <stdin>:26:0: /usr/include/x86_64-linux-gnu/sys/stat.h:320:12: note: in a call to function ‘mkdir’ declared here extern int mkdir (const char *__path, __mode_t __mode) ^~~~~ cc1: all warnings being treated as errors <stdin>: In function ‘syz_open_procfs.constprop’: <stdin>:530:41: error: ‘%s’ directive argument is null [-Werror=format-truncation=] <stdin>:85:110: note: in definition of macro ‘NONFAILING’ <stdin>:532:41: error: ‘%s’ directive argument is null [-Werror=format-truncation=] <stdin>:85:110: note: in definition of macro ‘NONFAILING’ <stdin>:534:41: error: ‘%s’ directive argument is null [-Werror=format-truncation=] <stdin>:85:110: note: in definition of macro ‘NONFAILING’ Use volatile for all arguments of syz_ functions to prevent compiler from treating the arguments as constants in reproducers. Popped up during bisection that used a repro that previously worked. Update #501
