<pre>Consider this common pattern:
class Frame {
Frame* FindFrame(uint32_t id) {
return const_cast<Frame*>(const_cast<const Frame*>(this))->FindFrame(id);
}
const Frame* FindFrame(uint32_t id) const;
};
The parens in the inlined functions are off, it needs to be:
return const_cast<Frame*>(const_cast<const Frame*>(this)->FindFrame(id));
cl.exe finds this:
e:\b\build\slave\win_x64_gn\build\src\mandoline\tab\frame.h(58) : warning
C4717: 'mandoline::Frame::FindFrame' : recursive on all control paths, function
will cause runtime stack overflow
clang doesn't. It should.</pre>
