2010-06-16 Thread Matthew Chambers 
xdebug built from latest SVN snapshot does not have this issue.
http://bugs.xdebug.org/view.php?id=586

Ubuntu is using the latest stable version already. Hopefully a new
stable release is made soon.

2010-06-15 Thread Matthew Chambers 
I should also say making the following change does not cause a segfault
and the code works as expected.

?php
//echo base64_encode('printf(output text);'); // Generates the string 
used below
$decoded = base64_decode('cHJpbnRmKCJvdXRwdXQgdGV4dCIpOw==');
eval($decoded); // Should print 'output text', and it does!
?
