Does any of the latest patches botched something here ?
I haven't changed anything in TR1 for some time. Seems OK here, what compiler/platform are you using?
We have the problem on Mac OS X using gcc 4.5 and on linux too.
I pinpointed the stuff to result_of. Using std::tr1::Result_of from functional.hpp take roughly 3s. Including boost/utility/result_of is less than 1s.
They're the same result_of, *unless* you've configured TR1 to use GCC's native result_of in which case the issue is out of our hands.... though of course tr1/functional.hpp #includes a whole lot of stuff that utility/result_of.hpp doesn't. John.
