     Type:  Bugs                                    |      Status:  new        
Milestone:  To Be Determined                        |   Component:  regex      
  Version:  Boost 1.46.1                            |    Severity:  Problem    
 Keywords:                                          |

 Compile and run the following code:

 {{{
 #include <boost/regex.hpp>

 int main()
 {
         boost::regex reg("(\\w++{3})*");
         return 0;
 }
 }}}

 This would cause boost to read from invalid memory and crash the program,
 leading to denial of service.

 The bug has been verified to exist in Boost 1.46.1, and also in trunk code
 as of Jun. 9.
