PCRE segfault on a big regular expression on a really big string (>17490
chars)
special parameters in php.ini file:
memory_limit = 64M
test script:
http://planet-service.fr/test2.php.gz
this script test a substring of the crashing string.
a loop do the test with this substring, and increase the size of the
string at each step and print out the size.

the end of the script (after the string itself).
