Bug ID: 64877
Summary: strange warning message from -Waddress
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: tromey at gcc dot gnu.org
I found a spot in firefox that tries to prevent hiding
using:
explicit ScopedGLWrapper(GLContext* gl)
: mIsUnwrapped(false)
, mGL(gl)
{
MOZ_ASSERT(&ScopedGLWrapper<Derived>::Unwrap == &Derived::Unwrap);
[...]
void Unwrap() {
...
}
gcc 5 warns about this assert:
/home/tromey/firefox-git/gecko-dev/gfx/gl/ScopedGLHelpers.h:35:54: error: the
address of ‘void mozilla::gl::ScopedGLWrapper<Derived>::Unwrap() [with Derived
= mozilla::gl::ScopedGLState]’ will never be NULL [-Werror=address]
MOZ_ASSERT(&ScopedGLWrapper<Derived>::Unwrap == &Derived::Unwrap);
^
The message here is strange. Whether or not the address can be NULL
is not an issue. I don't see why -Waddress ought to warn here at all.
