Assunto: [pcre-dev] Infinite loop by a certain pattern
Dear PCRE developers,
I found that infinite loop is produced by a certain pattern.
The following is a procedure of reproduction.
-------------------------------------------------
$ ./pcretest -C
PCRE version 7.9 2009-04-11
Compiled with
UTF-8 support
Unicode properties support
Newline sequence is LF
\R matches all Unicode newlines
Internal link size = 2
POSIX malloc threshold = 10
Default match limit = 10000000
Default recursion depth limit = 10000000
Match recursion uses stack
$ ./pcretest
PCRE version 7.9 2009-04-11
re> /(\x{ff}{0,2})*/8
-------------------------------------------------
Regards,
Guhin.
