Not sure the two are related, but I've also found bug 28108, please cross-check.

event simpler code that reproduces this crash: 
<?php 
 
function foo() { 
    $obj->plugins['function']['counter'][0](); 
} 
 
?> 
 
note: the function doesn't need to be called. it already 
crashes during parsing. 
 
with php-5.0.0RC3RC2 on linux i get:

I, too, am getting that same error message in the apache error log, but I can duplicate it differently.

Every call to bcmul(), I tried various values, and various values for bcscale), where either of the arguments is 0 will produce this error. 

$fStepX = '0.00750000000000000000';
bcmul($fStepX,0);

The system:
PHP 5.0, RC3 (Module, Pre-compiled , downloaded from php.net[Hurricane Electric mirror])
Windows 2000 Pro, SP4 [5.00.2195]
Apache 2.0.49 (Pre-compiled, downloaded from apache.org, No SSL)

Error message in Apache error log:
[Mon Jun 28 13:52:23 2004] [notice] Parent: child process exited with status 3221225477 -- Restarting.
[Mon Jun 28 13:52:23 2004] [notice] Parent: Created child process 2000

I wasn't sure whether I should give this a new bug report, or tack it on to one of the exisitings ones. I chose this one because it was the only relevant open report I could find.

I'm seeing this occur with Apache 2.0.52, PHP 5.0.2, and Windows 2003.

I'm not doing anything particularly special in the PHP. Most of the hosted files are 100% HTML going through PHP.

This has nothing to do with Apache since it's a crash in Zend.

This bug has been fixed in CVS.

Snapshots of the sources are packaged every three hours; this change
will be in the next snapshot. You can grab the snapshot at

Thank you for the report, and for helping us make PHP better.
