>Description:
"Internal Compiler Error" with following code (no further
messages from GCC):

struct Test {
  Test(const char *aString = 0);
  Test &set(const Test &arg = Test());
};

compiled with command "g++ test.cpp" and also with some
other compiler switches.
Works also if Test is a class.
>How-To-Repeat:

>Fix:

1.) Don't use default arg of Test::Test() within set():

struct Test {
  Test(const char *aString = 0);
  Test &set(const Test &arg = Test( "" /* <<< */ ));
};

2.) Define a real default constructor:

struct Test {
  Test()
  Test(const char *aString = 0);
  Test &set(const Test &arg = Test());
};
