Hi,
i've encountered a strange bug that causes webserver (Apache  1.3.26-1 in particular) to halt. I'm using PHP/Java combination I've built myself on Debian GNU/Linux (testing, kernel version is 2.4.20-pre7).

The killing code is here:

<?php
  mail("foo@bar.com", "111", "111");
  $system = new Java('java.lang.System');
  mail("foo@bar.com", "222", "222");
?>

The first mail is sent successfully, but not the second one.

The most amazing thing is, that eliminating a mail() or Java() call doesn't produce any problems. I mean, they work well separately. But when these calls are together (in my case - even on different PHP classes), it results a webserver lockup.

This has been tested on various PHP compilations starting from PHP 4.2.0 and up to the newest STABLE snapshot build.

The funniest thing is that this bug is ABSENT on my old PHP/Java build (4.1.2-1). Java version is the same on both cases:

mindas@kiras:~$ java -version
java version "1.3.1_02"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.1_02-b02)
Java HotSpot(TM) Client VM (build 1.3.1_02-b02, mixed mode)

If you need any more details on this, just drop me a message via e-mail.
