             Bug #: 53491
           Summary: internal compiler error: in
                    build_target_expr_with_type, at cp/tree.c:587
    Classification: Unclassified
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: k.lingaard@samsung.com


While doing something stupid (always the case, ain't it?) the compiler barfed
on me:

#include <queue>
#include <iostream>

using namespace std;

int main()
{
    typedef std::priority_queue<uint64_t, std::deque<uint64_t> > EventQueue;
    EventQueue m;

    uint64_t result = 0;
    result += m.pop();

    return 0;
}


Yeah, I know, you can't += on a function returning 'void', but, since the
compiler croaked, I thought I'd submit a minor bug on it.

This error also exists in gcc 4.8.0 20120520 (experimental) with the slightly
modified error location (-Wall -std=c++11):

Eh, eh, the compiler barfed and croaked (or a mix) because of this:

  gcc_assert (!VOID_TYPE_P (type));

Should be easy to fix, then.

This is enough:

struct M
{
  void pop();
};

int main()
{
  int result = 0;
  M m;

  result += m.pop();
}

looks like a Regression.
