--- Comment #7 from Philip R Brenan <philiprbrenan at gmail dot com> ---
A more compact example:
#include <stdio.h>
int * aaa() {return ({int a = 2; &a;});} // no warning unless -O2
int * bbb() { int b = 3; return &b;} // warning
int main(void)
{int *a = aaa(), *b = bbb();
fprintf(stderr, "AAAA %d\n", *a);
fprintf(stderr, "BBBB %d\n", *b);
return 0;
}
// AAAA 3
// Segmentation fault (core dumped)
Please provide the warning for line 2 (aaa) regardless of the level of
optimization?
