I am converting a perl cgi from perl-v5.001 (Solaris 2.5)`to perl-v5.005_03
(Solaris 2.6). The cgi contains code simular to that listed below.

Since this bug is causing serious problems, is there a patch or does the bug
exist in any other versions that are compitable with the Oracle 8 version of
Oraperl?

local ($a, $b, $c, %assoc);

$a = "a";
$b = "b";
$c = "c";

$assoc{one} = "11";
$assoc{two} = "22";

&print_values($a, $b, %assoc, $c);

sub print_values
{

  local($sub_a, $sub_b, %sub_assoc, $sub_c) = @​_;

  print " value passed #1 **$_[0]**\n";
  print " value passed #2 **$_[1]**\n";
  print " value passed #3 **$_[2]**\n";
  print " value passed #4 **$_[3]**\n";
  print " value passed #5 **$_[4]**\n";

  print "\n\n";

  print " sub_a **$sub_a**\n";
  print " sub_b **$sub_b**\n";
  for $key (keys %sub_assoc)
  {
  print " sub_assoc - Key​: $key Value​: $sub_assoc{$key}\n";
  }
  print " sub_c **$sub_c**\n";

  return;
}

When this code is executed by perl-v5.001 the following results are obtained.

value passed #1 **a**
value passed #2 **b**
value passed #3 **two**
value passed #4 **22**
value passed #5 **one**

sub_a **a**
sub_b **b**
sub_assoc - Key​: one Value​: 11
sub_assoc - Key​: two Value​: 22
sub_c **c**

When the code is executed by perl-v5.005_03 the following incorrect results
are obtained.

value passed #1 **a**
value passed #2 **b**
value passed #3 **two**
value passed #4 **22**
value passed #5 **one**

sub_a **a**
sub_b **b**
sub_assoc - Key​: one Value​: 11
sub_assoc - Key​: two Value​: 22
sub_assoc - Key​: c Value​:
sub_c ****

As one can see, perl has a bug such that it does not find the end of the
associative array correctly in the subroutine.

Thanks for any help in advance!
