This appears to have been fixed in passing by:

  commit fa8f4f85ec35b0f047603e5b90a788571f7141bd
  Author: Tony Cook <>
  Date:   Mon Jan 19 13:31:26 2015 +1100

  [perl #123554] avoid a crash from SvGROW(MEM_SIZE_MAX)

(Perhaps these tickets should be linked?)

This appears to have been broken only recently - in perl-5.19.1, from:

  commit cbcb2a16c528e483a6c8804d2d2daefecc1a0d3e
  Author: David Mitchell <>
  Date:   Sat Jun 8 18:24:51 2013 +0100

      add 1 to SvGROW under COW (and fix svleak.t)
