[Bug c/23474] New: gcc segfaults when inlined function is redefined after use

[ecc at cmu dot edu]

The following code causes Debian's gcc-4.0 to segfault:

static inline __attribute__((always_inline)) void f(void) {}
static inline void g(void) { f(); }
static inline void f(void) {}
void bug(void) { g(); }

gcc -v:
