Subject: Re: optimization/8913: [3.3 regression] ICE in simplify_gen_subreg, at simplify-rtx.c
X-SW-Source: 2002-12/txt/msg00706.txt.bz2
List-Id: <gcc-prs.sourceware.org>

Old Synopsis: internal compiler error: in simplify_gen_subreg, at simplify-rtx.c
New Synopsis: [3.3 regression] ICE in simplify_gen_subreg, at simplify-rtx.c

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Thu Dec 12 07:09:12 2002
State-Changed-Why:
    Confirmed. This is a regression, 3.2 compiled it fine.
    A slightly smaller testcase is
    -------------------
    template <class T> struct Ref { 
        Ref(int *);
        ~Ref();
    };
    
    struct User{
        User (Ref<int> obj) {};
    };
     
    void test() {
      User a (0);
    }
    -----------------------
    yielding
    tmp/g> /home/bangerth/bin/gcc-3.3-pre/bin/c++ -O -c x.cc
    x.cc: In function `void test()':
    x.cc:7: internal compiler error: in simplify_gen_subreg, at simplify-rtx.c:2673
    Please submit a full bug report,
    with preprocessed source if appropriate.
    See <URL:http://www.gnu.org/software/gcc/bugs.html> for instructions.
    
    My compiler collection tells me that the regression was
    introduced after Dec 1st this year, i.e. very recently.
