gcc-2.95 bug report

[Adam McKee <amckee at home dot com>]

gcc version: 2.95
OS: Linux 2.2.11 on an Intel P-166
gcc configuration: I got the compiler binaries from
                   ftp://contrib.redhat.com

Attached is a very small program that reproduces the problem.

Bug Description:

Here's what I get when I compile the attached program:

% g++ -o test test.cpp
test.cpp: In function `int main()':
test.cpp:24: warning: choosing `Object::operator char *()' over
`Object::operator const char *() const'
test.cpp:24: warning:   for conversion from `Object' to `const char *'
test.cpp:24: warning:   because conversion sequence for the argument is
better

There is a user-defined conversion directly from (Object) to (const char*)
so I think the compiler should just quietly use it.  I don't see why it
would regard the other conversion as better, since it will require a
conversion from (char*) to (const char*) afterward.

How can I disable this warning?  In the meantime I'll go back to
egcs-1.1.2.

I hope this helps, though I suspect this may have already been
reported.

#define NULL 0


class Object
{
public:
    operator char*()
        { return NULL; }
    operator const char*() const
        { return NULL; }
};


void
foo(const char* s)
{}


int
main()
{
    Object object;
    // next line generates a silly warning
    foo(object);
    return 0;
}
