            Bug ID: 25975
           Summary: clang -fsanitze=adderss prints waring only with gold
           Product: binutils
           Version: 2.35 (HEAD)
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gold
          Assignee: ccoutant at gmail dot com
          Reporter: dilyan.palauzov at aegee dot org

  Target Milestone: ---

I have clang and lld 10.0, ld.bfd 2.34.50.20200506, ld.gold 1.16 /
2.34.50.20200506 and i.c:

#include <stdio.h>
#include <stdbool.h>

int main() {
  bool b = 99;
  printf("a %i\n", b);
}

The question is, why only the last call emits a warning:
$ clang -fsanitize=address -fuse-ld=bfd  -o i i.c
$ clang -fsanitize=address -fuse-ld=lld  -o i i.c
$ clang -fsanitize=address -fuse-ld=gold -o i i.c
/usr/local/bin/ld.gold: warning: Cannot export local symbol
'__asan_extra_spill_
area'
