------- Comment #5 from stephane at magnenat dot net 2010-09-09 07:19 ------- Thank you very much for these explanations, thanks to your pointer I managed to make a working version, which I will attach to this bug as reference.
As a side-note, it is not easy to access C++ standard because the official ISO document is non free. While citing the section in the standard, did you refer to the N3092 draft (as linked from Wikipedia C++ page) or to the official ISO document? I found a draft of it at http://www.csci.csusb.edu/dick/c++std/cd2/template.html If I may suggest, it would be nice that g++ would be a bit more specific/clearer when reporting the error, because as there are few (if not none) freely available reference/documentation for complex templates processing, this would help users very much. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=45601
