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.
