from phpinfo();
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.

Check the phpinfo() output for this line: "Debug Build"
It should say 'yes' after it if you have a debug build running..

Now, i`m trying to make my code shorten. But, it's all the same i don`t
understand... why non-debug... why non snapshop.
I recompile my php yesterday. My last bt was made after php
modifications. My _current_ phpinfo():
PHP Version 5.2.4RC2-dev

Now, as I have told earlier:
I shall try to reduce a code;
I shall try to recompile my php once more time with support only this
extension`s: pdo, pdo_odbc, memcache, dom, iconv, ctype). Because,
performance of this extension is really used in code after execution
which, i having segmentation fault.

Also: Don't compile any extensions as shared like you're doing right
now. If you're not loading the extensions, don't compile them either!

Either you're not really running the debug build snapshot at all but
all the time the old 5.2.3 or something or you didn't compile
correctly.
phpinfo() is usually good place to check what is actually in use..
The backtrace would contain line numbers and such if it was a debug
build.

Ok. I would try make my code to shorten. But before, i have one
question: Why non-debug?! i use '--enable-debug' ?!
