>Description:
While playing a bit with c++/10108, I found this regression
on the 3.3 branch:
----------------------------------------------
struct Foo
{
template <typename>
struct Nested
{};
};
class Bar
{
Foo base ;
public:
typedef Foo::Nested type;
Bar() {}
Bar(const Bar& x)
: base(x.base)
{}
};
----------------------------------------------
pr10108.cpp:13: error: invalid use of template-name 'Foo::Nested' in a declarator
pr10108.cpp:13: error: syntax error before `;' token
pr10108.cpp:15: error: declaration does not declare anything
pr10108.cpp:15: error: missing ';' before right brace
pr10108.cpp:9: error: ISO C++ forbids declaration of `Bar' with no type
pr10108.cpp:17: error: ISO C++ forbids defining types within return type
pr10108.cpp:17: error: semicolon missing after declaration of `class Bar'
pr10108.cpp: In function `int Bar(const Bar&)':
pr10108.cpp:17: error: only constructors take base initializers
pr10108.cpp:10: error: `Foo Bar::base' is private
pr10108.cpp:17: error: within this context
pr10108.cpp:18: internal compiler error: Segmentation fault
Please submit a full bug report,
3.3 regression only (wrt 2.95), and does not show up in 3.4
(whose parser is much less aggressive and aborts
compilation earlier).
I rate this with the lowest priority and severity since it segfaults after several lines from the illegal code, and after decent error messages.
>How-To-Repeat:
Compile the above code.
