Reproducer:

struct obj_section
{
  void *the_bfd_section;
};

int condition;
struct obj_section sections[2];
struct obj_section *sections_end;

#define ALL_OBJFILE_OSECTIONS(objfile, osect)   \
  for (osect = sections; osect < sections_end; osect++) \
    if (osect->the_bfd_section == 0)                                    \
      {                                                                 \
        /* Nothing.  */                                                 \
      }                                                                 \
    else


int
main ()
{
  struct obj_section *osect;

  if (condition)
    ALL_OBJFILE_OSECTIONS (o, osect)
      if (osect == sections_end)
        return 0;

  return 0;
