Hello,

I'm generating a complex regular expression for removing word of  
textes, but now I get this exception:

terminate called after throwing an instance of  
'boost 
::exception_detail 
::clone_impl 
<boost::exception_detail::error_info_injector<std::runtime_error> >'
   what():  The complexity of matching the regular expression exceeded  
predefined bounds.  Try refactoring the regular expression to make  
each choice made by the state machine unambiguous.  This exception is  
thrown to prevent "eternal" matches that take an indefinite period  
time to locate.

Is there a solution to create any removing operation? I have got a  
vector with strings and I must remove each element on the texts, so I  
create a regular expression with "or"  and case-insensitive search ans  
use regex_replace to remove the words

Thanks

Phil
