--- Comment #10 from Fangrui Song <maskray at google dot com> ---
gold stills lacks some checks. A st_size=0 variant of Rafael's reproduce at #c3
% cat a.s
.long foo
% cat b.s
.global foo
.protected foo
.type foo, @object
#.size foo, 4 if st_size is 0
foo:
.long 0
% as a.s -o a.o
% as b.s -o b.o; gold -shared b.o -o b.so
% gold a.o b.so -pie
gold: error: a.o: requires dynamic R_X86_64_32 reloc against 'foo' which may
overflow at runtime; recompile with -fPIC
% gold a.o b.so # silent. it should error
