 g++: Internal compiler error

 Gcc-version:        gcc version 2.95.2 19991024 (release)

 uname -a :          CYGWIN_NT-4.0 MTPC386 1.1.0(0.16/3/2) 1999-12-26 
		     00:17:43 i686 unknown

 Compiler options:   g++ -Wall -o genfunc genfunc.cpp

 source:
 ----------------------------------------------
 // Generic function test
 template<class T> T create(T val)
 {
	 typename T::Y;   // Should produce same error as
	 Y instance(val); // typename T::Y instance(val); ???
	 return instance;		
 }

 int main()
 {
	 create<int>(2);	
	 return 0;
 }

 ----------------------------------------------

 This code should produce errors, but ends up in an infinite loop.
 Breaking this loop (^C) gives the following message:


 g++: Internal compiler error in `execute', at ../../gcc/gcc.c:2577
 Please submit a full bug report.
