PVS-Studio warning V519 for dmd-project

code *cdcond(elem *e,regm_t *pretregs)
{
  code *cc,*c,*c1,*cnop1,*c2,*cnop2;
  ....
  c2 = codelem(e22,&retregs,FALSE);
  c2 = cat(c1, fixresult(e22,retregs,pretregs));
  ....
}

Most likely this is what should be written here: c2 = cat(c2, ....);

This suspicious code was found in dmd-project project by PVS-Studio static code analyzer.
Warning message is:
V519 The 'c2' variable is assigned values twice successively. Perhaps this is a mistake. Check lines: 1860, 1861. cod2.c 1861
