           Summary: [tree-ssa] ICE with variable-sized arrays
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Keywords: ice-on-valid-code
          Severity: normal
          Priority: P1
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: reichelt@gcc.gnu.org
                CC: dnovillo@gcc.gnu.org,gcc-bugs@gcc.gnu.org

The following code crashes tree-ssa (20030620), just compile with "g++ -c":

-------------------------------------------------------------------------------
class A
{
    A( int );
};

A::A ( int i )
{
    int ar[1][i];

    ar[0][0] = 0;
}
-------------------------------------------------------------------------------

The error message is:
bug.cc: In constructor `A::A(int)':
bug.cc:10: internal compiler error: in make_decl_rtl, at varasm.c:801
Please submit a full bug report, [etc.]


Probably the same problem shows up with the following C-code snippet
(just compile with "gcc -c"):

-------------------------------------------------------------------------------
void foo(int i)
{
    int f[1][i];

    static void bar() { f[0]; }
}
-------------------------------------------------------------------------------

Here, the error message is:
bug.c: In function `foo':
bug.c:3: internal compiler error: in make_decl_rtl, at varasm.c:801
Please submit a full bug report, [etc.]

Since this is a regression on mainline, I set the priority to "P1".
