2Rob: my current version libxml2 = 2.6.26
Sorry. I have leave my office at long time. Today i give back to this
situation. And once again i have the same problem`s. I`m trying to make
a small sample of my code, but in the smallest variants i can`t catch
this troubles. I may proposal all our code for you... but it`s very big,
and we have a the same big DB under Sybase9.
my new bt from gdb:
0xb764c870 in xmlAttrSerializeTxtContent () from /usr/lib/libxml2.so.2

Not only would a reproducing script be helpful, but can you also
indicate what version of libxml2 you are using? That will at least give
me a starting point to see if this is an issue with DOM or not.

Rob, can you check this out please? (It might be something more general
than just DOM issue but we need to begin somewhere :)
And Danil, can you try provide the shortest possible example script
that causes this crash?

Debug Build yes
I have catch reason of segmentation fault.
I have some big code. Very big...
And i have a some objects extends of DOMDocument in that.
f.e
class A extends DOMDocument {
private $_obj; // other object
...
}
$a = new A();
...
very many logic`s
...
$a = null;
This code was finished with segmentation fault.
But if...
class A extends DOMDocument {
private $_obj; // other object
...
public function __destruct() {
$this->_obj = null;
}
}
It`s everything ok.
or
Without modification`s in class A declaration, we don`t do it "$a =
null;" it`s all correct too.
