--- Comment #2 from Alexander Cherepanov <ch3root at openwall dot com> ---
But gcc seems to be better than clang in arranging compound literals in memory
so here is a gcc-only testcase with them:
----------------------------------------------------------------------
#include <stdio.h>
int main()
{
unsigned long u, v;
{
u = (unsigned long)&(int){0};
}
{
v = (unsigned long)&(int){0};
}
printf("diff = %lu\n", u - v);
printf("eq = %d\n", u == v);
}
----------------------------------------------------------------------
$ gcc -std=c11 -pedantic -Wall -Wextra -O3 test.c && ./a.out
diff = 0
eq = 0
----------------------------------------------------------------------
gcc x86-64 version: gcc (GCC) 10.0.0 20191230 (experimental)
----------------------------------------------------------------------
