I have

[hjl@gnu-4 linux]$ readelf -sW libclang_rt.asan-x86_64.a | grep
__asan_extra_spill_area
   185: 0000000000001dc4     0 NOTYPE  LOCAL  HIDDEN     6
.annobin___asan_extra_spill_area.start
   186: 0000000000001e0d     0 NOTYPE  LOCAL  HIDDEN     6
.annobin___asan_extra_spill_area.end
   385: 0000000000001dd0    61 FUNC    GLOBAL HIDDEN     6
__asan_extra_spill_area
     7: 0000000000000000     0 NOTYPE  GLOBAL DEFAULT  UND
__asan_extra_spill_area
[hjl@gnu-4 tmp]$ clang -fsanitize=address -fuse-ld=gold i.o 
[hjl@gnu-4 tmp]$ readelf -sW a.out| grep __asan_extra_spill_area 
  4269: 00000000004c73c4     0 NOTYPE  LOCAL  HIDDEN    13
.annobin___asan_extra_spill_area.start
  4270: 00000000004c740d     0 NOTYPE  LOCAL  HIDDEN    13
.annobin___asan_extra_spill_area.end
  7505: 00000000004c73d0    61 FUNC    LOCAL  HIDDEN    13
__asan_extra_spill_area
[hjl@gnu-4 tmp]$ 

What do you get on __asan_extra_spill_area?
