[Bug c++/61172] New: C++11: ICE with invalid call to template class

            Bug ID: 61172
           Summary: C++11: ICE with invalid call to template class
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tobi at gcc dot gnu.org

I'm seeing this bug with all g++-4.7 I have access to.  There seems to be no
duplicate in bugzilla, even though there are a few similar bugs they are fixed
in 4.7.0 the latest.  Even if this is fixed in trunk (I cannot check this right
now), adding a testcase may be sensible:

$ cat t.cc
#include <vector>

struct foobar {
    int a;
};

int main(){
    std::vector<foobar> foo;
    //Should fail: foobar has no constructor with one argument
    foo.emplace_back(0);
}
$ g++ t.cc
t.cc: In function 'int main()':
t.cc:10:9: error: 'class std::vector<foobar>' has no member named
'emplace_back'
$ g++ --std=c++11 t.cc
'
Internal compiler error: Error reporting routines re-entered.
Please submit a full bug report,
with preprocessed source if appropriate.
See <https://trac.macports.org/newticket> for instructions.

(I see that it mentions macports.  To avoid all confusion: I also see this ICE
it with unmodified gcc-4.7.2 on Linux.)

Thanks! I wonder which option I missed when I was searching for duplicates :(
