Bug description:Interactive php-cli crashes if include() is used in
auto_prepend_file
Description:
------------
Hello,
this bug may be related to bug #49000. php-cli crashes in interactive mode
if
you do an include() in auto_prepend_file. An example will explain it better
(see
test scripts):
% php -d auto_prepend_file=prepend.php -a
Interactive mode enabled
test 1
test 2
Ran out of opcode space!
You should probably consider writing this huge script into a file!
This was tested with PHP 5.4.5 (from ports) on FreeBSD 8.1 and PHP 5.4.4
(from
Debian Git repository) on Ubuntu 12.04.
No error if the include file is missing (only the usual warning).
Also, I got another very weird case...
The provided prepend_segfault.php segfaults instead of the error above:
% php -d auto_prepend_file=prepend_segfault.php -a
Interactive shell
test 1
zsh: segmentation fault (core dumped) php -d
auto_prepend_file=prepend_segfault.php -a
But there is no segfault and no errors if I remove "$toto = 1".
If I replace one (or both) if/elseif conditions with true or false, it
execute
the script 2 times instead on 5.4.4 (and it segfaults on 5.4.5):
% php -d auto_prepend_file=prepend_towtimes.php -a
Interactive shell
test 1
test 1 bis
test 1
test 1 bis
test 2
php >
Of course if I remove the include() line, everything is back to normal.
Something is very wrong, isn't it? :)
Test script:
---------------
// prepend.php => weird error
<?php
echo "test 1\n";
include("include.php");
?>
// include.php
<?php
echo "test 2\n";
?>
// prepend_segfault.php => segfaults
<?php
$toto = 1;
if (php_sapi_name() == "cli") {
} elseif (php_sapi_name() == 'fpm-fcgi') {
}
echo "test 1\n";
include("include.php");
?>
// prepend_towtimes.php => script is executed two times (5.4.4) or
segfaults (5.4.5)
<?php
$toto = 1;
if (true) {
} elseif (false) {
}
echo "test 1\n";
echo "test 1 bis\n";
include("include.php");
?>
Expected result:
----------------
No weird behaviour and not segfaults when I use include() in an
auto_prepend_file
in interactive mode.
