According to the ISO C standard, compound literals in functions are objects
with automatic storage
duration. The following test case modified such an object, so in this test
case the value should be 1 the
first time through the loop and 77 the second time. Instead we see 1 the first
time.
#include <stdio.h>
int main() {
int i = 0;
int* p;
top:
p = &((int) {1});
printf("%p %d\n", p, *p);
*p = 77;
if (i++ == 0) goto top;
return 0;
}
