PHP Bug Type: Scripting Engine problem
Bug description: token_get_all gives wrong result

Description:
------------
This is bug 29761, I'd like to see it reopened.
(it might also be 33093, not sure)

Create the two php files in 'reproduce code'.
Point your browser to 'test.php'. First time you should get the expected
result, second the actual result.

If you have many apache threads, you might need to refresh a few times
until the error occurs.

I've tested and reproduced this on:
* Windows XP: Apache/2.0.52 (Win32) PHP/5.0.5
* Linux: Apache/1.3.33 (Debian GNU/Linux) PHP/4.3.10-15

(yes, error.php is supposed to have a parser error)

thanks for your time

/Linus

Reproduce code:
---------------
error.php:
<?php

print('abc'
;

?>

test.php:
<?php

header('Content-Type: text/plain');

$first = token_get_all('<?php $a=$b;');
print_r($first);

require('error.php');

?>

I should also add that this is not reproducable with cli version of php
(probably because it's always a new process?).

Only with apache module have I seen this behaviour and once it get's
into 'error mode' it usually stays that way.

This is probably related to the strange reports about highlight_string
doing weird things. If you can, please try to run this:
sudo valgrind /path/to/apachesrc/src/httpd -X
and request the same file twice. If valgrind gives any errors, please
put the trace online and provide a link here. With this we see if it is
indeed multiple requests causeing this problem.

New Comment:

Here you'll find some valgrind outputs:
http://x.mccabe.nu/public/traces/

I didnt build apache from source, so I used:
valgrind --log-file=./trace1 /usr/sbin/apache -X
I hope its good enough anyway?

The result can be seen in trace1.log, trace2.log and trace3.log.

trace1.log shows was on a request on a small php file that did not
include any parsing error or use token_get_all.

trace2.log shows the request of earlier mentioned 'test.php' requested
once.

trace3.log shows the request of 'test.php' requested twice and the
second time it gave the wrong result.

traceX_full.log is the same request all over again, but using:
valgrind --leak-check=full --log-file=./trace1 /usr/sbin/apache -X

Hope this helps and let me know if there's anything else i can do!

What configure line did you use? What MPM you use in Apache2?

Here you'll find some valgrind outputs:
http://x.mccabe.nu/public/traces/

I didnt build apache from source, so I used:
valgrind --log-file=./trace1 /usr/sbin/apache -X
I hope its good enough anyway?

The result can be seen in trace1.log, trace2.log and trace3.log.

trace1.log shows was on a request on a small php file that did not
include any parsing error or use token_get_all.

trace2.log shows the request of earlier mentioned 'test.php' requested
once.

trace3.log shows the request of 'test.php' requested twice and the
second time it gave the wrong result.

traceX_full.log is the same request all over again, but using:
valgrind --leak-check=full --log-file=./trace1 /usr/sbin/apache -X

Hope this helps and let me know if there's anything else i can do!

This is probably related to the strange reports about highlight_string
doing weird things. If you can, please try to run this:
sudo valgrind /path/to/apachesrc/src/httpd -X
and request the same file twice. If valgrind gives any errors, please
put the trace online and provide a link here. With this we see if it is
indeed multiple requests causeing this problem.

I should also add that this is not reproducable with cli version of php
(probably because it's always a new process?).

Only with apache module have I seen this behaviour and once it get's
into 'error mode' it usually stays that way.

I tried with php5-win32-latest: Apache/2.0.52 (Win32) PHP/5.1.0RC2-dev

Same behaviour...

Please try using this CVS snapshot:

I did another test and altered test.php to look like:

<?php

header('Content-Type: text/plain');

register_shutdown_function('term');

$first = token_get_all('<?php $a=$b;');
print_r($first);

require('error.php');

function term()
{
apache_child_terminate();
}

?>

After that it gives the correct result every time.
This is of course not an ideal solution, but I thought it might give
yet another hint that the failing has something to do with the previous
script's error.

Also, I've tried with other errors than parsing errors (like doing
division by zero, trigger_error, etc) but nothing else seems to get php
into 'error mode'.

New Comment:

I put my phpinfo's in
http://x.mccabe.nu/public/traces/

one for the linux box and one for the windows box.

On windows I have apache2, binaries supplied by apache foundation.
On Linux I use debian's apache packages, but it's apache 1.3
