          Issue ID: 23582
           Summary: undefined identifier `__builtin___memset_chk`
           Product: D
           Version: D2
          Hardware: x86_64
                OS: Mac OS X
            Status: NEW
          Severity: enhancement
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: doob@me.com

Compiling the following C code:

#include <string.h>

void foo()
{
    memset(0, 0, 0);
}

Results in the following error:

foo.c(5): Error: undefined identifier `__builtin___memset_chk`

If I run the C code manually through the preprocessor this is the relevant output:

void foo()
{
    __builtin___memset_chk (0, 0, 0, __builtin_object_size (0, 0));
}

I'm using macOS 13.0.1, DMD v2.101.1 and Xcode 14.2.
