Hello,

Again, I have a segfault with RecursiveDirectoryIterator when I extend
it. This time, I have a very strange value on my SplFileInfo extension
(subclass). When I var_dump the value, I have UNKNOWN:0. This is not a
string, not null, not false, just UNKNOW:0, without type. Any idea of
what is it?

Thanks :-).

Unknown is an unknown value in a structure when a zval is not properly
set. Most likely you didn't call the parent's constructor.
To bad, the constructor has been called :-(.

The error is here: https://github.com/hoaproject/Iterator/blob/master/Recursive/Directory.php#L125. This is a line that causes the segfault. And at line 109, $this->getRelativePath() returns UNKNOWN:0. But if I var_dump $this->_relativePath directly (without using the method), I have a real value. I can't explain this.
