Yes, its works on Linux. This bug is Windows only.
On Apache/1.3.29 (Win32) PHP/4.3.10 this code works fine too.

I have used Dimox's code on a Windows 2000 server running IIS and PHP
4.4.2 and have reproduced the problem. The regular expression commands
on this server combination seem to be susceptible to crashing like
this.

Can I get trial version of MSVC6? If it exist, can you add link for me?
I'm only web-programmer and I has no tools for C++
development/debugging.
Maybe you can run file test_bug.php on your oun PC with this tools and
generate this debug backtrace?

While i symlificate the code i forgot to remove \%\> from example and
posted text for parsig was too small to cause error. I found, that
block content must be more tan 1330-1360 simbols to couse script crash
- until this values it works fine! I increased all "memory size" values
in php.ini and in the code, but problem still exist.
Changed code:
$text = '<block name="name1">
something
