To bad, the constructor has been called :-(.
The error is here:=20
https://github.com/hoaproject/Iterator/blob/master/Recursive/Directory.ph=
p#L125.=20
This is a line that causes the segfault. And at line 109,=20
$this->getRelativePath() returns UNKNOWN:0. But if I var_dump=20
$this->_relativePath directly (without using the method), I have a real=20
value. I can't explain this.
