Description of problem:
sorry the summary is so big ;)
when i try to use a nested class as an argument to a constructor for the 
enclosing class, g++ gives a segmentation fault.  if i move the nested 
class outside of the enclosing class, or if i don't use the " = 
ServiceInformation()", or even if i use " = ServiceInformation(0)" it 
works fine.

I guess it's not a huge problem, since it's really easy to work around, 
but i got really scared when gcc segfaulted.

How reproducible:
Always

Steps to Reproduce:
1. make the following file "testes.h":
class testes {
public:
	struct ServiceInformation {
		ServiceInformation(long lPID = 0)
			:PID(lPID) {};
		long PID;
	};
	testes(const ServiceInformation &svcinf = ServiceInformation());
};

2. make this file testes.cpp:
#include "testes.h"

testes::testes(const ServiceInformation &svcinf) {
}

testes::~testes() {
}

3. compile the program:
g++ -c testes.cpp
	

Actual Results:  [sdallamura@vader testes]$ g++ testes.cpp
In file included from testes.cpp:1:
testes.h:9: Internal error: Segmentation fault.
Please submit a full bug report.


Expected Results:  it should have worked >:O
