Found the culprit :)
Although never actually called for this instantiation, interval_map<
int, float >, the intersection functor is set to inplace_et and
appears in the code that is called when

map_1 & map_2;

is applied. I have added partial instantiations for inplace_et<float>.
This is a quickfix, but fully fuctional. The more proper fix will be
done within the next days. You can update file
https://svn.boost.org/svn/boost/sandbox/itl/boost/itl/functors.hpp
from the sandbox to get the fix.

Thanks,
