>Organization:
OPNET Technologies
>Environment:
System: SunOS zweistein 5.6 Generic_105181-20 sun4u sparc SUNW,Ultra-5_10
Architecture: sun4

	
host: sparc-sun-solaris2.6
build: sparc-sun-solaris2.6
target: sparc-sun-solaris2.6
configured with: ../gcc-3.0.4/configure  : (reconfigured) ../gcc-3.0.4/configure --with-gnu-ld
>Description:
The code compiled and worked on M$ VC6 SP5, and I'm pretty sure it's legal
(although more indirect than useful).
I verified with truss that I'm only using gcc-3.0.4 headers.

>How-To-Repeat:
Compile this:

        #include <string>
        #include <map>
        template <typename T> class Foo {
            typedef std::map<std::string,T>::allocator_type::reference bar;
        };


>Fix:
Use instead:

            typedef T*& bar;

Synopsis: ICE on nested type in template declaration

State-Changed-From-To: open->analyzed
State-Changed-By: lerdsuwa
State-Changed-When: Wed May 22 06:57:59 2002
State-Changed-Why:
    ICE confirmed.  The code is illegal.  The line
                typedef std::map<std::string,T>::allocator_type::reference bar;
    should be replaced by
                typedef typename std::map<std::string,T>::allocator_type::reference bar;
