[Bug c++/27819] New: [4.0/4.1/4.2 regression] ICE casting static const variables

[reichelt at gcc dot gnu dot org]

The following valid code snippet causes an ICE since GCC 4.0.0
(it was wrongly rejected in GCC 3.4.x):

======================================
struct A
{
    static const char i = 1;
};

template<int> struct B
{
    static const int j = A::i;
    int x[int(j)];
};

B<0> b;
======================================

bug.cc:9: internal compiler error: in build_c_cast, at cp/typeck.c:5252
Please submit a full bug report, [etc.]

This is related to PR 26266.

------- Comment #1 from bangerth at dealii dot org  2006-05-31 02:31 -------
I confirm the ICE with 4.0.x. With 4.1.x, we get a duplicate error message:

g/x> /home/bangerth/bin/gcc-4.1-pre/bin/c++ -c x.cc
x.cc:12: error: variable-size type declared outside of any function
x.cc:12: error: variable-size type declared outside of any function

I'm not completely sure whether the testcase is invalid (I suppose the cast
can not be part of a constant expression). icc accepts the code.

W.
