           Summary: Generation of debug symbols leads to internal compiler
                    error
           Product: gcc
           Version: 4.8.1

test case leading to internal compiler error

Enabling the generation of debug symbols leads to an internal compiler error
(segmentation fault). A preprocessed minimal example is attached. The problem
is reproducible in g++ versions 4.7.2, 4.7.3, 4.8.0 and 4.8.1. Version 4.7.1 is
the last version where I did not encounter any problems.

// code
template<typename T, long unsigned int N>
struct array {
    T data[N];
};

template<typename T>
struct derived {
    typedef long unsigned int size_type;
    static const size_type n = 42;

    array<int, n> a;
};

// compile
$ g++ -g -Wall -Wextra -save-temps test-case.cpp
test-case.cpp:12:2: internal compiler error: Segmentation fault
 };
