Well it works for me with the Boost-1.33.1 install supplied with current 
cygwin, the test program is:

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

int main()
{
   try{
      boost::regex 
e("(?<=GU.*?TACTAAC.{20,40}AG|^)?(GU.*?TACTAAC.{20,40}AG|$)");
   }
   catch(boost::regex_error e)
   {
      std::cout << "Caught a regex_error" << std::endl;
      std::cout << e.what() << std::endl;
   }
   catch(std::exception e)
   {
      std::cout << "Caught a std::exception" << std::endl;
      std::cout << e.what() << std::endl;
   }
}

and then:

$ g++ -I /usr/include/boost-1_33_1 t.cpp -lboost_regex-gcc-mt
Info: resolving vtable for boost::regex_errorby linking to 
__imp___ZTVN5boost11regex_errorE (auto-import)

$ ./a
Caught a regex_error
Invalid regular expression

Which is what I would expect in that case.

HTH, John.
