Suppose I have a source code like this:
#include <stdio.h>FILE *p;int main(void) { p;}... which will compile (using gcc) without any errors or warnings – unless I turn on -Wall, in which case a statement with no effect warning will be output.
However if the code went like this:
#include <stdio.h>int main(void) { stderr;}... no warnings would be shown regardless of -Wall.
Am I missing something here?
gcc version 9.3.0
