Any arch

Problem Description:

gcc fails with an ICE (internal compiler error) when compiling a particular c++ code:

internal compiler error: in make_rtl_for_nonlocal_decl, at cp/decl.c:5067

How Reproducible:

Always

Steps to reproduce:

Build the following program:

namespace
{
template <typename T>
class A
{
virtual T f1() { return c; }
static const T c = 0;
};
A<int> v;
}

g++ -c junk.cpp

Actual Results:

Compilation fails with the following error:

% gcc -c junk.cpp
junk.cpp: In instantiation of ‘const int <unnamed>::A<int>::c’:
junk.cpp:7:   instantiated from ‘T<unnamed>::A<T>::f1() [with T = int]’
junk.cpp:11:   instantiated from here
junk.cpp:8: internal compiler error: in make_rtl_for_nonlocal_decl, at cp/decl.c:5067
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://bugzilla.redhat.com/bugzilla> for instructions.
Preprocessed source stored into /tmp/ccOodQtT.out file, please attach this to your bugreport.

Expected Result:

Compilation should finish successfully

I have committed a minimal patch based on the above in a private branch 'private-SR2023672-branch' and created test packages for the customer. The customer has verified that the patch fixes the issue. Patch and test packages available here:
