#6213: Escaping close parentheses doesn't work in boost::regex

     Type:  Bugs              |      Status:  new    
Milestone:  To Be Determined  |   Component:  None   
  Version:  Boost 1.47.0      |    Severity:  Problem

------------------------------+---------------------------------------------
 Currently I am running Boost 1.47 on Scientific Linux 6 and cannot get the
 escaped close parentheses to match in a very simple expression.  I can
 remove the escaped close parentheses and the regular expression will
 match, but with the escaped close parentheses, we never can get the if
 statement to work.  I can put a small work around in our codebase, but I
 would expect this feature to work.  Below is a example snippet of code:

 {{{
 #!div style="font-size: 80%"
   {{{#!C++
 void MyFuction(const std::string& val)
 {
   boost::regex  expr1("(.*)\\((.*)\\)");
   boost::regex  expr2("(.*)\\((.*)");
   boost::cmatch matches;

   if(boost::regex_match(val.c_str(), matches, expr1)) {
     //never will get in here
   }

   if(boost::regex_match(val.c_str(), matches, expr2)) {
     //will get in here when we expect it to
   }

 }
   }}}
 }}}

 I appologize if there's something on my side that I'm missing, but I
 searched around and really can't find anything in our code base that would
 indicate its our code base and not boost::regex.
