This piece of code:

<?php
    $p = pdf_new ();
    pdf_open_file ($p);
    pdf_close ($p);
?>

Gives these leaks:
pdf.c(306) :  Freeing 0x0820B324 (65536 bytes), script=3pdf.php
Last leak repeated 2 times

This code:
<?php
    $p = pdf_new ();
?>

Gives this leak:
pdf.c(306) :  Freeing 0x08200D54 (2116 bytes), script=3pdf.php
Last leak repeated 1 time

You should call PDF_delete($); at the end of a script containing PDF functions. This will cleanup the resources allocated by PDFlib.

This might be done in the function given to zend_register_list_destructors_ex (_free_pdf_doc), but as I don't know documentation when this is called it is not yet integrated into the source pdf.c.

For the moment I donot know how to decide whether PDF_delete already was called when _free_pdf_doc() is called.
