While generating the virgin wiki page (the first dynamically generated page of a wiki which is created after configuring the config files), PHP exits with a stack overflow:
"PHP has encountered a Stack overflow".

This may also be a script error, but from the error message I assume it is rather not so I am posting this here as well.

The PHP version in use is 4.3.4, running on IIS 6 (on Win 2003 Server) as ISAPI module. Further information on the PHP configuration is available on request. However the installation is mostly based php.ini-recommended.

As all the other bug reports mentioning a stack overflow are  rather old I assume this may be a new one, otherwise I am sorry and would really welcome a hint.

FYI: I reported the same bug to PHPWikis bug tracker at

PHP does not give this message ever, it must be a phpwiki error messages and thus you'll have to contact its authors.

A quick check with google shows this is obviously not a phpwiki issie:

One can quickly reproduce this error message with PHP5.2 and Windows Server 2003 with the following:

function a() { a(); }

The above recursion issue is already known to the PHP team, and is currently regarded as unfixable, though this error message does not appear on Apache servers. It thus appears that IIS is generating the error message.
