From: "jan.smets at nokia dot com" <gcc-bugzilla@gcc.gnu.org> To: gcc-bugs@gcc.gnu.org Subject: [Bug c/100671] override-init suppressed in 'two shot' compilation when initializer macro/value is defined in system header file Date: Wed, 19 May 2021 09:14:45 +0000 [thread overview] Message-ID: <bug-100671-4-ONYrIJ12C5@http.gcc.gnu.org/bugzilla/> (raw) In-Reply-To: <bug-100671-4@http.gcc.gnu.org/bugzilla/> https://gcc.gnu.org/bugzilla/show_bug.cgi?id=100671 --- Comment #1 from Jan Smets <jan.smets at nokia dot com> --- Another one we've had problems with is quite similar. The example below is a void function trying to return a value. #if 1 /* NULL defined in a system header file => warning in "one shot" compilation. => no warning in "two shot" compilation. */ #include <stddef.h> #else /* always warns */ #define NULL (0L) #endif void test(void) { return NULL; }
