Ok, I will make a backtrace then and post it here.
But until I do it, this is last what I found out:
Remember comment line:
// From DB....
Well if I remove JUST one dot it becomes:
// From DB...
and NO crash occurs!!!
If I ADD just one dot it becomes:
// From DB.....
and NO crash occurs!!!
What does it tell you, at a first glance?
I think, that it is, a specific number of string symbols, in .php file
that represent PHP(code) script itself, that brings core down

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
And how we suppose to know what you are doing then?
You can try to create a backtrace, maybe there is an obvious problem
which can be seen in it.

Script has 145 lines of code and loads 5 custom classes and 3 extra
files.
What you propose is, as I've just found, most likely impossible.
Reason is that crash won't appear if I remove ANYTHING from script.
At one line I removed COMMENT!
// From DB....
Which doesn't affect PHP's code in ANY way.
To my shock everythhing restored to normal.
Exactly this fact makes me unable to ISOLATE few lines of code for
crash reproduction.
