Not AFAICS: otool -rv has
make-temp-file.o:
Relocation information (__TEXT,__text) 54 entries
address pcrel length extern type scattered symbolnum/value
[...]
00000257 False byte n/a VANILLA True 0x000003c0
which corresponds to this in the disassembly (otool -tv):
00000253 addb %al,%cl
00000255 sbbl $0xc3,%esi
00000258 leal 0x02(%esi),%eax
In the .s file, we have
addb %al, %cl
sbbl $3+_vartmp, %esi
leal 2(%esi), %eax
and
.zerofill __DATA,__bss2,_memoized_tmpdir,4,2
.const
.align 2
_vartmp:
.byte 47
[...]
So no zero-size symbol in sight.
I'm attaching preprocessed input, .s and .o files so you can see for
yourself.
