This is a bug report for perl from nick@​bactrian.ni-s.u-net.com,
generated with the help of perlbug 1.26 running under perl 5.00503.

Found it - it is part of change 6489. The changes stated intent
is to remove main​:: prefix from warnings. Looks like select() was
changed by over-zealous global edit.

Checked in change 7003 which does​:

==== //depot/perl/pp_sys.c#180 (text) - //depot/perl/pp_sys.c#181 (text) ==== content
@​@​ -1083,7 +1083,7 @​@​
  else {
  GV **gvp = (GV**)hv_fetch(hv, GvNAME(egv), GvNAMELEN(egv), FALSE);
  if (gvp && *gvp == egv) {
- gv_efullname4(TARG, PL_defoutgv, Nullch, FALSE);
+ gv_efullname4(TARG, PL_defoutgv, Nullch, TRUE);
  XPUSHTARG;
  }
  else {

All tests still pass for me.
