[Bug c++/37910] New: Must use 'this' to access member

[lyricsfan at lycos dot com]

g++ 4.3.2

linux 2.6.11.7 (gentoo)

Using built-in specs.
Target: i686-pc-linux-gnu
Configured with: ../gcc-4.3.2/configure --prefix=<something>
Thread model: posix
gcc version 4.3.2 (GCC)

g++ test.cpp

Error when condition detailed at the end is met:

test.cpp: In constructor 'Y<T>::Y()':
test.cpp:5: error: 'i' was not declared in this scope

test.ii

# 1 "test.cpp"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "test.cpp"
template<class T> struct X {
    int i;
};
template<class T> struct Y : public X<T> {
    Y() { i = 100; }
};

int main() {
    Y<double> y;
}

test.s

    .file   "test.cpp"

***

The above code does not correctly compile if 'this->' is removed ('double' and
'int' are dummy types), while g++ 3.3.6 works as expected.

Also not working: g++ 3.4.6 (no other version tried).

one more thing: when inheriting from, say, X<int>, all is fine.

Yes, this is the right behaviour, conforming to the C++ Standard. It has been
announced in the 3.4.x release notes:
