have you ever seen this error?

When I use boost.regex
it throw this exception
clone_impl {error_info_injector {std::runtime_error} }
I don't know why and who throw this,And how to fix the problem, but I did find out that if I try-catch this exception and do nothing in catch block, the program work fine. However because the code causing this exception, when repeatly run, will throw several this exception and after several throwing without dealing with, the program shut down.

So what is the matter?

BTW, i really don't know where to post a thread relating to boost regex, so I post here. Anyone can give the answer or point out a webpage that demonstrate this problem will be appreciated!

And do I need to change this thread to other subforum, feel free to give the exact subforum's name and I will convert this thread.

Thanks.
