Using Apache 1.3.20, PHP 4.0.6 as a module, on Solaris 2.5.1.

Everything else seems to work except the round() function. Any call to round() seg faults the Apache process. Backtrace:

The CGI standalone PHP executable, built from the same code, works fine.

Does this problem still occur with 4.1.1 and/or the latest CVS?
 [2002-01-09 16:00 UTC] raunn at volterra dot com 
Yep. Just compiled 4.1.1 and still the same problem.
 [2002-01-09 16:05 UTC] derick@php.net 
Can you make a static apache module, compiled with --enable-debug (non-stripped) and provide a backtrace?

Derick

Here you go:

Now we need short & complete script that causes this segfault.
Under my Linux

<?php
round(123.123);
?>

does not segfault.
BTW, what is your Apache version?
 [2002-01-14 13:00 UTC] raunn at volterra dot com 
Your simple script causes the segfault for me.

I am running Apache 1.3.20.

No feedback was provided. The bug is being suspended because
we assume that you are no longer experiencing the problem.
If this is not the case and you are able to provide the
information that was requested earlier, please do so and
change the status of the bug back to "Open". Thank you.

Thank you for taking the time to report a problem with PHP.
Unfortunately your version of PHP is too old -- the problem
might already be fixed. Please download a new PHP
version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.
