My code has a function which should but does not return a value. MSVC reports that as "error C4716: 'fooBar' : must return a value". cl.exe returns an exit code "2". Creator understands that the build fails and shows a red build progress bar.

But the build issues list shows a warning for the missing return. That is wrong.
See attached screenshot.

This is what cl.exe pumps into stdout:

qmlstandalone\main.cpp(54) : error C4716: 'findUnresolvedModule' : must return a value
