Dear Monks,

I am having a problem with associated tables using the BerkeleyDB module. Here is a snippet of code: 

  my $table = BerkeleyDB::Btree->new(
    -Filename => "$home/$tableName/$tableName",
    -Compare  => sub { my($a, $b) = @_; return $a <=> $b; }, # numeric
    -Flags    => DB_CREATE,
  ) or die "Could not open \'$home/$tableName/$tableName\' ... ";

  my $db = BerkeleyDB::Btree->new(
     -Property => DB_DUP,        
     -Flags    => DB_CREATE,
     -Filename => "$home/$tableName/$dbName",
     -Compare => sub { my($a, $b) = @_; return $a cmp $b; }, # ascii
    ) or die "Could not open \'$home/$tableName/$dbName\' ... ";

  $table->associate($db, \&key_sub);

The key_sub extracts one field from the record using split, and I want to use that as a secondary index. I have no error messages when the first record is inserted, but when I insert a second record, I get error messages that indicate that the numeric comparison function, and not the ascii comparison function, is being used for the secondary table. 
Argument "w61" isn't numeric in numeric comparison (<=>) at /home/Acct
+Table.pm line 80.
Argument "w60" isn't numeric in numeric comparison (<=>) at /home/Acct
+Table.pm line 80.

The line number in the error messages above is the line where the numeric comparison is defined. Is this a bug in the perl BerkeleyDB module, or is it a bug in the db library itself? Is there a work-around for it? Thanks for your help.
