Yes, doubly curly braces are no longer necessary. The following works as expected wirh #gcc 12, 14, and #clang 19. Pet has no previous clang at paw, it was too buggy.

Enough #meow, here's the test:

#include <stdio.h>

void cleanup(char*)
{
puts("cleanup\n");
}

int main(int argc, char** argv)
{
for (unsigned i = 0; i < 5; i++) {
[[ gnu::cleanup(cleanup) ]] char c = 0;
printf("iteration %u\n", i);
}
return 0;
}

Pet noticed there's no memory leaks without doubly curly braces in loop bodies. Which means gnu:cleanup works for each iteration in #gcc, but pet haven't checked that yet.

This did not work in #clang 16. Probably it was (and maybe still is) a compiler bug.

Anyway, it's safer to use doubly curly braces.
