[Bug c++/14383] New: Class member incorrectly treated as template-name in function template

[Bug c++/14383] New: Class member incorrectly treated as template-name in function template

[timb at bluearc dot com]

Feed this snippet to gcc -c :

----- test.cpp
struct t;

struct A
{
    int t;
};

template <typename> void f(A a)
{
    a.t < 0;
}
-----

It says:

test.cpp: In function `void f(A)':
test.cpp:10: error: parse error before `;' token

It seems to be taking a.t to be a template name, and therefore < as the start 
of a template argument list instead of less-than. a.t is not a template 
(whether or not there is also a struct t), so this is wrong. The problem does 
not appear if f is not itself templated.

What an interesting feature, and how funny that this is the first 
time I see this bug. 
 
Alas, this is fixed in mainline and 3.4, and since I get the same 
failure back to 2.95, this is also not a regression. In other words, 
it is not going to be fixed in 3.3.x.
