I get the following error message:

Warning: Problem with method call - please report this bug in line xyz.
This error message comes from /Zend/zend_execute.c, line 1638.

This error occurs in our applications framework with many intermingled classes on both Linux and Windows 2000 Boxes (I have not checked on Solaris yet). I have not been able to produce a simple set of classes producing this error. The basic structure of what our code is doing is:

class CUi {
function httpHeader($p_disableGzHandler = false) {
}
function htmlHead($p_subDirs = false) {
	if ( ! isset($this) ) {
		// this is the static pseudo initialization
		$this->m_subDirs = $p_subDirs;
	}
	CUi::httpHeader(); // this is the line where the error occurs
}
}
CUi::httpHeader();

If I move the CUi:httpHeader() call done from within htmlHead() above "if (! isset($this) )" the error does not occur.

I am sorry to not be able to provide better information. I would not have reported this bug, but it explicitly asks to report it, so here we go.

I have had a similar situation when assigning to $this:

function seek_and_destroy($where_ary) {
  if (!isset($this)) {
    $this = new ecdGroupedNews(); // this is the line where the warning is pointing to
  }
 ...
}

this yields:

Warning: Problem with method call - please report this bug in /usr/home/anarcat/data/web_pages/www/anarcat.ath.cx/php/ecdGroupedNews.inc.php on line 44

well, it's not *exactly* the same thing, but there is a similarity: both problems occur when referencing $this in shadowy conditions (ie. unset($this)).

Also note that morphing the code into:

        function seek_and_destroy($where_ary) {
          if (!isset($this)) {
            $foo = new ecdGroupedNews();
          } else {
            $foo = $this;
          }

supressees the warning, of course, so it is a proper workaround, for me.

i get it  al so on windows me 

this is the furst php bug that badders me :(

I have experienced this error on php 4.3.11 installed via Debian APT. I was calling DB::isError from PEAR inside another static method (Release::create), that I had written myself.

Perhaps calling a static method from within another static method is causing this problem? I haven't got time to build a test suite though...
 [2005-05-29 11:49 UTC] oracle dot shinoda at gmail dot com 
If I change the DB::isError calls to $this->_db->isError, the script runs correctly, which is why I suggested the double-static method call being a problem.

Thank goodness for PHP4's lazy OO implementation, else I'd be stuck with a massive refactoring job now!
 [2005-05-30 02:03 UTC] oracle dot shinoda at gmail dot com 
Actually, I have found one reason why it may not work: I was referring to a member variable ($this->_db) inside my static call!!

This should throw a fatal error, not a bug report warning, though I see that you won't be fixing it since PHP5 is out and you won't fix bugs in PHP4's OO support unless they occur in PHP5.

I don't have access to PHP5 so I can't tell if it is a problem there or not.
