as far as I can tell, there should be no warning for snprintf(), as there is no
warning for the other functions. I checked all the PRs in PR84774 and didn't
find any this would be duplication.
Of course I am not a language lawyer, so my understanding of 'restrict' might
be incorrect; but the warning is at least inconsistent:
- only snprintf() warns
- the s[] must be an array
- both i/j indices must be variables
- -Wrestrict alone is not enough to trigger this -Wrestrict warning at -O0

It seems the issue is in:

   0x00401389 <+225>:   push   $0x10

(gdb) p $rsp
$48 = (void *) 0x7fffd3c0

(gdb) p/x $rdi
$50 = 0x7fffd3c0

that "push" overwrites the destination of the just finished "rep movsd"; this
is probably specific to -Oz

[Bug libgcc/114327] `-CST % 1` is wrong for _BitInt()

[zsojka at seznam dot cz via Gcc-bugs]

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=114327

--- Comment #3 from Zdenek Sojka  ---
It's not only % 1; wrong results are also for:
  B x = foo (3, -0x9e9b9fe60);

or for

B
foo (char c, B b)
{
  return b / c;
}


  B x = foo (-0x6, 0); /* 0 / -6 = 0 */

in all these cases, the result is the same: -1 << 64.

[Bug tree-optimization/113962] [14 Regression] ICE: in exact_div, at poly-int.h:2156 with -O -mavx512f

--- Comment #3 from Zdenek Sojka  ---
(In reply to Andrew Pinski from comment #2)
> Most likely a dup of bug 113967

I am sorry for the confusion; the bugzilla stopped responding while creating
this PR for the first time, and since I there wasn't any new message in the
gcc-bugs mailing list, I thought the PR wasn't created, and I created PR113967
instead.
