           Summary: ICE after `array_ref' not supported by dump_type
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

        ReportedBy: bangerth at dealii dot org
                CC: gcc-bugs at gcc dot gnu dot org

Here's a small testcase that ICEs:
--------------------------
template <int> struct S{};

template <int N> S<sizeof(new double[N])> f () {}

template S<4> f<2>();
--------------------------

With present mainline, we get:
tmp/gg> ../build-gcc/gcc-install/bin/c++ -c x.cc
x.cc:3: sorry, unimplemented: `array_ref' not supported by dump_type
x.cc:3: sorry, unimplemented: `array_ref' not supported by dump_type

Internal compiler error: Error reporting routines re-entered.
Please submit a full bug report,

Nothing fancy with the ICE. It's just trying to emit the same sorry message 
another time, but within an error diagnostic (the template instantiation is not 
right), so it doesn't work.
In other words, the ICE will go away when the sorry is fixed. Let's keep this 
only for the sorry.

The sorry() is another problem with dumping new-expressions. There are too many 
different trees called NEW_EXPR, so dump_expr gets confused.

We now get a plain ICE (a segfault) on mainline.

Gaby, did you mean to assign this to yourself? It's still assigned to unassigned...

Fixed on mainline by Mark's patch

http://gcc.gnu.org/ml/gcc-cvs/2004-06/msg00888.html

Do we want to add the testcase to the testsuite?

Shouldn't adding testcase almost fall under the "obvious" rule?

Yes, I think we do.

I also believe I've seen instances of this PR several times so
that we care about not going back again.

Thanks

Adding testcases is obvious, except when it is not :-)
In this case, yes, adding the testcase is obvious.

Ok. Are you going to commit it? It's your testcase. ;-)

I don't keep CVS writable trees around, so would appreciate if someone else could 
do it.
