Subject: Re: c++/7456: SegFault with deducting template args from variably sized arrays
X-SW-Source: 2003-01/txt/msg00687.txt.bz2
List-Id: <gcc-prs.sourceware.org>

Old Synopsis: #243 gcc2.96 - template problems
New Synopsis: SegFault with deducting template args from variably sized arrays

State-Changed-From-To: open->analyzed
State-Changed-By: bangerth
State-Changed-When: Fri Jan 10 17:24:09 2003
State-Changed-Why:
    I doubt this is legal, but it shouldn't segfault either.
    In any case, this still happens even with present 3.4, as
    well as with all other versions in between.
    
    Testcase:
    ---------------------------
    template <int H, int W>
    void function(int (&wmarker)[H][W]) {};
    
    void method() {
      int h=1, w=2;
    
      int array[h][w];
      function(array);
    }
    --------------------------
