Custom error handling segs faults on PHP 5.1 or older #196

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Use a system with PHP 5.1
2. Update simplesamlphp to revision newer than 1643
3. Try to access the index page

What is the expected output?

Normal welcome page of SimpleSAMLPHP

What do you see instead?

A blank page. And in Apache logs I see a line like this:

child pid 13149 exit signal Segmentation fault (11)

Please use labels and text to provide additional information.

This is due the following bug in PHP itself:

http://bugs.php.net/bug.php?id=41209

which has been fixed in PHP 5.2.

I'll attach a patch that fix this issue.

Same segfault on debian / php 5.2.6-1+lenny3. The patch from Lorenzo fixes the 
issue
by removing calls to custom error handling. (version check needs to be updated)

I am currently running php 5.2.6-1+lenny3, and have never seen this crash. What 
is 
necessary to trigger it?

I had this issue with the openid module : customer.php triggers the crash.

Could you test the attached patch, and see if it still crashes?

I cannot fix this bug without feedback, since I do not have this problem.

Sorry, I have no free time right now to test this again. I hope to be able to 
give
feedback in the next weeks.

Considering that we have more or declared PHP version < 5.2 to be unsupported 
by simpleSAMLphp, I am closing this bug.
