The following program consists of two classes, both with a
parametrized method. Depending on the parameter type g++ the
compilation fails or not...
-- snip --
class E1 {
public:
template <class T>
void print(T bla) { };
};
class E2 {
public:
// same as above but with a reference
template <class T>
void print(T& bla) { };
};
void foo1() {
E1 e;
// works
e.print("hurz");
// works too
e.print(23);
};
void foo2() {
E2 e;
// works
e.print("hurz");
// fails!
e.print(23);
};
int main () {
};
-- snip --
riff /tmp> g++ -Wall temptest1.cc
temptest1.cc: In function `void foo2()':
temptest1.cc:33: error: no matching function for call to
`E2::print(int)'
temptest1.cc:13: error: candidates are: void E2::print(T&) [with T =
int]
Exitcode 1
riff /tmp> g++ --version
g++ (GCC) 3.3.2 20031005 (Debian prerelease)
[...]
This behavoir is at least inconsistent and I believe it to be
buggy. However, the Intel Compiler fails on the same line, so maybe
it's a special case in the C++-specs?!
Cheers

Hi,
upstream says the error message is correct (or at least cannot be
improved reasonably), so closing.
