The seg fault happened with

gcc version 4.2.4 (Ubuntu 4.2.4-1ubuntu3)

unintentionally I left out two semicolons in the test case, the corrected test
case is:

$ cat test.c
struct R
{
        char c;
};

struct R
{
        struct R r;
};

int main(void)
{
        struct R r;

        return 0;
}

$ gcc test.c
test.c:7: error: redefinition of ‘struct R’
gcc: Internal error: Segmentation fault (program cc1)
