Bug Type: Reproduceable crash
Description: PHP switch() with crashes the Apache child with a SegV (11)
Tried on PHP4.0.4 on both machines that were running PHP4.0.3pl1 and that I
experienced the problem with, the problem seems to be solved. Now the error is
correctly reported as a parse error in the first include (e.g. with my previous
example, the myfunctions.inc file)
I don't know if it was fixed specifically, but however, this 'bug' is squashed. All
other versions of software compiled into the HTTPd are the same as before when I did
experience the crash. 4.0.4 indeed makes the problem 404 (not found) :>
Thank you for checking into it,
Derek

I can not reproduce this with latest CVS. Please try PHP 4.0.4 and reopen
this bug report if problem still exists with it.

My last comments did not accurately give an indication of how to reproduce the bug. I
didn't realise at the time that it's the placement of the code that causes the
problem. To reproduce the problem , put the code segment I gave (basically a parse
error) in a function that is included from an included file.
e.g.
function myFunction($var) {
switch ($var) {
case 1,2:
}
}
in a file myfunctions.inc
allfunctions.inc includes file myfunctions.inc
index.html includes allfunctions.inc
access index.html -> crash
I also noticed I did not have the Zend optimizer running or even loaded on the machine
that I have this problem on. I can try the latest snapshot version, but here is a
backtrace from 4.0.3pl1.
Thanks,
Derek

Does not crash for me.
Could you try latest version from snaps.php.net?
Could you please also generate crash trace as described at
http://bugs.php.net/bugs-generating-backtrace.php?
Did you try it without the Optimizer?

The script:
switch ($variable) {
case 1,2:
}
crashes. I typed it accidentally instead of this (which works as I intended):
switch ($variable) {
case1:
case2:
}
I have Apache 1.3.14 compiled with PHP4.0.3pl1 as well as mod_ssl (openssl) and mm.
Compiled from scratch on the same machine as it is running. I'm also using the Zend
Optimizer 0.99 for PHP 4.0.3.
Script to make Apache, PHP and all other items:
cd /usr/src/apache
./configure
cd /usr/src/php
./configure --with-apache=../apache --with-my-sql ; make ; make install
cd /usr/src/openssl
./config ; make
cd /usr/src/mm
./configure --disable-shared ; make ; make install
cd /usr/src/mod_ssl
./configure --with-layout=Del --with-apache=../apache --with-ssl=../openssl --wi
th-mm=../mm --activate-module=src/modules/php4/libphp4.a
cd /usr/src/apache
make; make install
