             Bug #: 51841
           Summary: iterator weirdness. I couldn't tell you what's going
                    on here
    Classification: Unclassified
           Product: gcc
           Version: 4.6.2
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: marcus-yass@ihug.co.nz


Whenever I start using vector::iterators I start running into a variety of
completely unhelpful[probably delusional] compile errors. Attached is a simple,
perfectly reasonable source file that provokes such an error.

compilation: g++-4.6 -std=c++0x 1.cpp

As you can see you get comparable results from using a bare sub-class that has
a similar position as vector::iterators.


In the less trivial source file I got the complaint "porousVect.cpp:67:36:
error: ‘std::vector<T, std::allocator<T> >::iterator’ is not a type".

It so /is/. If you'd like to look at that one too I'll strip it down and post
it for you.

Are you using auto; if not try using auto instead of naming the full type? If
you don't want to do that then do you have the typename keyword in front of
std::vector<T>::iterator ; if not then that is your bug.

void actv(vector<T>::iterator in){

You are missing the typename keyword.

Thanks a bunch, Andrew. I didn't know about this. The internet hasn't served as
a very good teacher for me.
