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. I don't have access to a 64-bit machine, so I need the backtrace to take a look.

Don't be scared, this regular expression is real parser for my templates-engine, and it works with other operation systems. The result depends on Subject, so with '$var' it works well, but if '$var[anything]' then crashes.
