bjam msvc-7.1 release cxxflags=-arch:SSE2
But that doesn't seem to reproduce the problem :-(
I can reproduce from the IDE though, so there must be some other combination
of command line arguments that's required as well I guess. Unfortunately
the error message gives you no idea which instantiation of that template is
responsible - and since it's used ubiquitously in the library - it's hard to
know where to begin to look for the problem.
There are also some other issues I had with VC7.1, where depending upon the
order in which templates are instantiated some of them may not be found at
link time :-(
