           Summary: ICE on parsing initialization list of const array member
           Product: gcc
           Version: 3.2.2
            Status: UNCONFIRMED
          Severity: minor
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ElGringo@gmx.at
                CC: gcc-bugs@gcc.gnu.org

Member:       const int val[2];
Constructor:  Foo::Foo (...) : val((int[]) {...})
results in:
init.cpp: In constructor `Foo::Foo(int, int)':
init.cpp:12: Internal compiler error in build_modify_expr, at cp/typeck.c:5516

works fine with Constructor: Foo::Foo (...) : foo((const int[]) {...})

(i don't understand why i need the casting, but syntax error without...)

Created an attachment (id=4140)
 --> (http://gcc.gnu.org/bugzilla/attachment.cgi?id=4140&action=view)
produces ICE. would work fine with "(const int[])" in initalization list

I would be glad if sombody can tell me why I need the casting operator when
initializing arrays. What do I make wrong?

I see it on the mainline (20030601), 3.3.1 (20030526), 3.2.3, 3.0.4 but I do not get an ICE 
but an error on 2.95.3 so this is a regression:

On the mainline (20030802) with checking turned off, GCC accepts this code.

Is this code really invalid as a gcc extension (from C99) of style C99 inits for structs/
arrays is being use?

The regression (ICE) in PR 11063 was introduced or exposed by this patch:

--- gcc/gcc/cp/ChangeLog ---

2001-01-03  Jason Merrill  <jason@redhat.com>

        * init.c (build_default_init): New fn.
        (perform_member_init): Split out from here.
        (build_new_1): Use it.  Simplify initialization logic.
        (build_vec_init): Take an array, rather than a pointer and maxindex.
        Speed up simple initializations.  Don't clean up if we're assigning.
        * cp-tree.h: Adjust.
        * decl2.c (do_static_initialization): Remove TREE_VEC case.
        * parse.y (new_initializer): Return void_zero_node for ().
        * typeck.c (build_modify_expr): Handle getting a CONSTRUCTOR.
        * typeck2.c (digest_init): Only complain about user-written
        CONSTRUCTORs.

The regression hunt took place on i686-pc-linux-gnu using this test
case, included here because it's slightly different from the one in the
attachment:

class Foo
{
private:
  const int val_[2];

public:
  Foo(int, int);
};

Foo::Foo(int v0, int v1)
  : val_((int[]) {v0, v1})
{
}

Before this patch the test case got these messages:

11063.C: In constructor `Foo::Foo(int, int)':
11063.C:12: incompatible types in assignment of `int[2]' to `const int[2]'

With this test case I get the same ICE with a recent mainline compiler
built with and without checking disabled.
