in reply to implicit numeric conversion isn't

It shouldn't be taint; taint is checked for system calls, but not for simple operations like modulus.

It does work okay here (RHEL 3, perl 5.8.0).

When I run it as follows: 

use strict;
use warnings;

use RRDs;
my $datafile = "temp.rrd";
my $lupdate  = 12345;
my $hash     = RRDs::info($datafile);
my $step     = $hash->{'step'};
my $mid      = $lupdate % $step;
print $mid;

... it prints 45 as expected.

Possibly the error is elsewhere in your code...?

    Try it this way (get last update from the hash as well): 
      my $hash    = RRDs::info( $datafile );
  my $hStep   = $hash->{'step'};
  my $lupdate = $hash->{'last_update'};
  my $mid     = $lupdate % $hStep;
  print( "$lupdate % $hStep = $mid\n" );

      That works here, too. It prints (at the moment) 187.   Devel::Peek shows both $hStep and $lupdate are integers (IOK set): 
      SV = IV(0x9f83208) at 0x9ee8b6c
  REFCNT = 1
  FLAGS = (PADBUSY,PADMY,IOK,pIOK)
  IV = 300
SV = IV(0x9f8320c) at 0x9ee8b78
  REFCNT = 1
  FLAGS = (PADBUSY,PADMY,IOK,pIOK)
  IV = 1163531587

        Thank you for trying. I split out my code, and it works as expected. Therefore something is happening earlier in the code, perhaps somewhere before or during the call to the Cricket libraries, which call this code as a referenced subroutine.
