I have the same problem OS: Fedora 9 uname -r :2.6.27.24-78.2.53.fc9.i686 php -v: 5.2.9(cli) Everything worked fine until I made the following combination of bash-commands: su;pear upgrade-all;<trying to get an external libary to work>;pecl install pdflib;pear install File_PDF;yum -y install php-Zend*; The External libaries was fpdf(aquired from their homepage). Trying to get the pdf-routines to work caused a segfault. Looking back all startet using pear upgrade-all ; So I uninstalled php and all of it's components and manually clensed the system from any reamainds of php-files(required for the interpreter to run) and Config-files using locate,updatedb and rm -fr. And made several reboots. After that I reinstalled php step by step. yum -y install php; worked well. The interpreter runs good but as soon as I execute require_once(),include() or require() using the Interactive shell I get a Segmentation fault. This fault remained after I reinstalled the pearcomponents. yum -y install php-pear*; The strange things is that the skripts running on my Apache(Version 2.2.9(Unix)) are executing normally but grepping through the logs of the server I get a stacktrace everytime I executed a script containing one of the 3 functions mentioned earlier. sincerly ------------------------------------------------------------------------ [2008-08-08 14:12:48] lbarn...@php.net Reproducing: $ php -a Interactive shell php > include "example2.php"; WTF?! ------------------------------------------------------------------------ [2008-08-08 01:39:03] mazzarelli at gmail dot com In case it wasn't clear, I forgot to mention what seems to be happening. In interactive mode, upon reaching the "if (false)" containing a try/catch block, the interactive session tries to include the file again. This never stops and in continually includes the file over and over. If you change the function to print out $i, you will see this clearly. If the condition is "true", it exhibits the correct behavior. False, or a condition that evaluates to false, introduces the bug. ------------------------------------------------------------------------ [2008-08-07 23:52:52] mazzarelli at gmail dot com Description: ------------ when running a bit of code from the command line, it works. Running the same code interactively causes it to hang. Reproduce code: --------------- <?php // example1.php if (false) { try {} catch (Exception $e) {} } ?> <?php // example2.php function stop_the_madness () { static $i; if (++$i > 1) exit("WTF?!\n"); } stop_the_madness(); if (false) { try {} catch (Exception $e) {} } exit("A-OK\n"); ?> Expected result: ---------------- In the first snippet, nothing should happen. But when that is in a file, and require_once'ed from the interactive shell, it hangs. In the second example, when ran from CLI, it says A-OK. But when ran interactively, it says "WTF?!" ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45749&edit=1
