problems with PHP 4.4.1 (extract from the TinyLetter)

A bad PHP bug which appears with Php 4.4.1 (this is the last version), and disappeared with Php 4.4.2-dev, makes troubles with Array pointers.

This bug makes array functions key() and current() to return bad values when used on a variable with several references. 
Reference to the bug:
  http://bugs.php.net/bug.php?id=35084

Since this bug has no easy workaround and is already fixed in the next     Php Dev version, we just recommend to not use PHP 4.4.1 for any of you
applications.

This bug has a big impact on TinyButStrong because Array pointers are used to merge Array data and also to merge several blocks with the same data source.
But you have to take car that this bug will probably have several impacts on other PHP libraries.

Hum well... the very last TBS version now available for download brings a patch for this PHP 4.4.1 bug.
