The following does not cause a seg fault.

$ts = '112005';

$t1 = substr($ts, 0, 2);
$t2 =  substr($ts, 2);

$cal->initCalendarDMY(1, $t1, $t2 );

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc.

If possible, make the script source available online and provide
an URL to it here. Try to avoid embedding huge scripts into the report.

I am sorry this was my fault, I thought I had checked everything but missed something. I apologize for wasting your time.

Hmm.. I'm still curious what was the reason for the segfault.
Could you provide a short but complete reproduce case?
Or at least tell me how exactly did you fix it?
