            Bug ID: 60081
           Summary: Internal compiler error: Error reporting routines
                    re-entered.
           Product: gcc
           Version: 4.7.3
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org

preprocessed source

It appears that declaring a class member to have type a vector of unique_ptr's
is the reason for this bug, but could not verify details.

I found this internal error, too, and found this Bug (60081) as a "possible
duplicate" of the one I was creating. I think it may be a duplicate as I
certainly have std::vector<std::unique_ptr<....> >s. I'll change them to
something else and see where I can go from there. Thanks for filing this bug
and beginning a diagnosis, Mr. Manilov!

Right, changed unique_ptr to shared_ptr in my code base and the error goes
away. Have you seen if this bug still appears on a 4.8 build ?

Another reproduction

For what it's worth, I just uploaded bugreprt.gz which has more code that
reproduces the issue along with the makefile I used, etc.

Here is a simple way to reproduce the bug:

==============================
#include <vector>
#include <memory>

int main() {
        std::vector<std::unique_ptr<int>> v;
        std::unique_ptr<int> px(new int (1));
        v.push_back(px);
}
==============================

There is a bug in the code: push_back tries to copy the given element by
default. This should return an error along the lines of "Call to deleted copy
constructor of std::unique_ptr". Instead it gives ICE.

A solution to the bug in the code is to explicitly call std::move like so:

==============================
#include <vector>
#include <memory>

int main() {
        std::vector<std::unique_ptr<int>> v;
        std::unique_ptr<int> px(new int (1));
        v.push_back(std::move(px));
}
==============================

Fixed a lot of time ago, in 4.8.0.
