Running the following code​:

  my(@​oidsToQuery) = my(@​indices) = ();   __END__

results in the following message​:

  Bizarre copy of ARRAY in aassign at - line 1.

This code above is part of Cricket (cricket.sf.net).

The message is only generated in 5.8.4 on Debian/Linux\, but not in 5.8.1\, 5.8.0\, or 5.6.1 on Linux or Solaris. So\, it seems to be a recently introduced bug.

Thanks for your report.

This bug was introduced in perl 5.8.4 and has been fixed by Change #22781. The fix will be part of perl 5.8.5\, which will be released in July.
