Subject: Re: c++/10558: [3.3 regression] Segfault on illegal use of template without template args
X-SW-Source: 2003-04/txt/msg01426.txt.bz2
List-Id: <gcc-prs.sourceware.org>

Old Synopsis: ICE in c_expand_expr in  c-common.c:3715
New Synopsis: [3.3 regression] Segfault on illegal use of template without template args

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Wed Apr 30 01:11:21 2003
State-Changed-Why:
    Confirmed. Though the error happens even earlier (in a 
    tree check function) if checking is enabled. Here's a
    smaller testcase:
    --------------------------
    namespace NS {
      template <typename> struct C {
          template <typename U> C (U);
      };
    
      struct X {
          X(C<int>);
      };
    }
    
    NS::X x(NS::C);
    --------------------------
    It crashes 3.3 as follows:
    g/x> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -c x.cc
    x.cc:11: internal compiler error: Segmentation fault
    Please submit a full bug report,
    
    3.4 gives a useful error message on this as well as the
    original testcase. 2.95 crashes on this one, but it doesn't
    crash on the original testcase, so this is a 3.3 (not 3.4)
    regression.
