Bug description: segfault with RecursiveIteratorIterator
Description:
------------
When accidently comparing a the iterator created by
RecursiveDirectoryIterator against a string PHP segfaulted. This is new to
5.1.2 (worked under 5.1.1 and I was unaware of the issue with my code).
There are obvious workarounds for this so no major panic.
Removing the 'if':
if($file!="."&&$file!="..")
stops the segfault.
Unfortunately I only have EMT64/Debian64 servers available so I am unable
to test this for cross-platform compatibility, and I was unable to find
any exact matching bugs (closest were a few stack corruptions).
This occurs when the script is executed on the command line and via
apache2. I have saved straces should they be requested.
Reproduce code:
---------------
$this->dir = new RecursiveIteratorIterator(new
RecursiveDirectoryIterator("."),true);
foreach($this->dir as $file){
// works...
echo $file->getPathName()."\n";
// segfauls...
if($file!="."&&$file!="..") echo $file->getPathName()."\n";
}
Expected result:
----------------
./dir/
./dir/file1.ext
./dir/file2.ext
....
Actual result:
--------------
Segmentation Fault.
