When use #^(A{1}B)+$# instead of #^(A{1,2}B)+$#
testcase returns 1 - no crash

...and I tested Windows 7 only (32-bit and 64-bit)

...but using apache module phpinfo also says:
pcre.backtrack_limit 1000000
pcre.recursion_limit 100000

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?
