The following code (taken from §12.5 "Free Store" of the C++ Standards, with
some simplifications) fails to compile:

struct B
{
    virtual ~B() { } // line 5
    void operator delete(void*, size_t);
};

test.cpp:5: error: no suitable 'operator delete' for 'B'

(The code taken directly from the C++ standard without modification fails as
well)

if you remove the size_t parameter, it succeeds

This kind of code exists in KDE's khtml.

A full testcase:
struct a
{
  void operator delete (void*, unsigned int);
  ~a();
};

void g(a *b)
{
  delete b;
}

Actually my testcase is invalid as "unsigned int" is not always size_t.  In
fact if I change it to "unsigned long" for x86_64 and PPC-darwin, it passes in
4.1.0 20060208 and 4.2.0 20060507.

It also works in 4.1.2 20060529 and in 4.2.0 20060604.

This works for me so closing as invalid.  And yes I changed ~a to virtual ~a
also and it still works.

Can you provide a source which cause does not error out because size_t?

Works in 4.2.0 20060507 and 4.1.0 20060208 and 4.1.2 20060529.

And works as of today in 4.1.2 20060608 so this is still invalid.

I am hitting this bug in gcc 4.0.3, trying to compile MySQL 5.0.19 and 5.0.24.

MySQL compiles fine with gcc3.3 and gcc3.4, so this is definately a problem in
4.0.3 itself.
