            Bug ID: 18745
           Summary: --start-lib --end-lib  picks a weak symbol definition
                    ahead of a strong symbol definition
           Product: binutils
           Version: 2.26 (HEAD)
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gold

Is this a bug?

foo.cc

#include <stdio.h>

__attribute__((weak))
int foo() {
  printf("This is weak\n");
}

int main() {
  foo();
}

bar.cc

#include <stdio.h>
int foo() {
  printf("This is strong\n");
}

$ g++ -c foo.cc bar.cc
$ ld.gold --start-lib foo.o bar.o --end-lib  ..
$ ./a.out
This is weak

I would have expected the strong definition to be kept.
