Bug Type: PHAR related
Operating System: Linux 2.6.28
PHP Version: 5.3CVS-2009-06-09 (snap)
Assigned To: cellog
New Comment:
two problems:
1) this file is not bzipped, in fact it is not compressed at all
2) this file is not a phar archive, it is a plain tar archive
and the segfault can't be reproduced even when I bzip the resulting
archive, so I suspect your system is borked.
If you want to provide a bzipped phar archive that actually reproduces
the segfault, that would be fine.
Better yet, please provide a script similar to the following:
<?php
$a = new Phar('cli.phar.bz2');
$a->setStub(file_get_contents('cli.php'));
$a->compress(PHAR::BZ2);
?>
that creates an actual phar archive that is broken.

File can be found here : http://www.ajeux.fr/cli.bz2
It contains a single file cli.php
Download this file and launch this:
<?php
include 'cli.bz2';
?>
Now that I'm more familiar with Phar, I'm not sure this is phar
related. I'm just including something that is absolutely not a php
readable file, don't I ?
Same SEGFAULT (ie same line/file) when including a bz2 archive that
contains a file containing the string 'iiiaaaoouu'; (yes, this is not a
php syntax, I can see that ;) ).
What do you think ?

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external
resources such as databases, etc. If the script requires a
database to demonstrate the issue, please make sure it creates
all necessary tables, stored procedures etc.
Please avoid embedding huge scripts into the report.
I can't reproduce this, and the download link has expired.
Can you also please say from which directory you are running the
script?

Description:
------------
Trying to include a specific .phar leads to a segfault under Linux.
The .phar is a bz2 archive, and very small (just one file inside).

Bug seems to happen with any .phar.bz2 file.
Reproduce code:
---------------
<?php
include 'cli.phar.bz2';
Expected result:
----------------
working :)
