str_repeat('AB',200) do not crash
str_repeat('AB',300) crashes - browser freeze about 4sec and info - browser can
not display site

Windows-only, I assume? Apache uses PCRE as well, so perhaps Apache on Windows
is
resetting the PCRE limits? I assume it doesn't crash if you reduce the 300
there
to something smaller?

I checked recursion-limit:
pcre.backtrack_limit 1000000
pcre.recursion_limit 100000
On fastCGI or direct php.exe testcase.php does not crash.
When use Apache 2.2.21 with php module with the same php.ini
testcase.php crash apache.
Now I am at home. The same crash like at work - two other machines.

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 think it is probable because of :
http://www.php.net/manual/en/pcre.configuration.php#ini.pcre.recursion-limit

php.exe testcase.php does not crash
