  This test generates "bad free" warnings when run under
  PERL_DESTRUCT_LEVEL.  This file merely serves as a placeholder
  for investigation.

  Complex regular subexpression recursion limit (%d) exceeded

        $_ = 'a' x (2**15+1); /^()(a\1)*?$/ ;

  (The actual value substituted for %d is masked in the tests so that
  REG_INFTY configuration variable value does not affect outcome.)
