    l1_a.c
```
void a()
{
  b();
}
```
l1_rem.c
```
void rem()
{
  printf("This rem will be a lazy symbol for lld, but will be disarded by gnu ld.\n");
}
```
l2.c
```
void b()
{
  rem();
  c();
}
```
l3.c
```
void rem()
{
  printf("This rem will cause duplicate symbol error with lld.\n");
}

void c()
{
  printf("end.\n");
}
```
Way to reproduce the error:
```
clang -c *.c
ar rcs lib1.a l1_a.o l1_rem.o
ar rcs lib2.a l2.o
ar rcs lib3.a l3.o
clang -fuse-ld=lld main.o -l1 -l2 -l3 -L.
```
Output:
```
./lib1.a: lazy definition of rem
./lib2.a(l2.o): reference to rem
./lib1.a(l1_rem.o): definition of rem
ld.lld: error: duplicate symbol: rem
>>> defined at l1_rem.c
>>>            l1_rem.o:(rem) in archive ./lib1.a
>>> defined at l3.c
>>>            l3.o:(.text+0x0) in archive ./lib3.a
clang-14: error: linker command failed with exit code 1 (use -v to see invocation)
