[clang-format] Misformatted address-of operator after cast on 20 versus 19

[rmarker]

While testing on the release branch for 20, I discovered this formatting change from 19.1.0.

Using 19.1.0:

::gluTessCallback(tesselator.get(), GLU_TESS_COMBINE_DATA,
                  (GLvoid(FONM_GLU_STD_CALLBACK *)())&CallbackCombine);

Using 20 (8c25748):

::gluTessCallback(tesselator.get(), GLU_TESS_COMBINE_DATA,
                  (GLvoid(FONM_GLU_STD_CALLBACK *)()) & CallbackCombine);

Is GLvoid a macro? What's it defined as? It's likely that 19.1.0 got it right by chance, and you need to add something like Macros: [GLvoid(a)=void(*)] to your config file after bcd586b.

GLvoid isn't a macro. It is a type provided by OpenGL. I.e. via typedef void GLvoid.
Though, adding that macro configuration you suggested, does cause the old formatting to return? Though, I wouldn't think that would be necessary in this instance.
The only macros in that example are FONM_GLU_STD_CALLBACK and GLU_TESS_COMBINE_DATA.

Looking further, I found another example that seems like it could be the same issue. But this one doesn't have any macros present.

19.1.0

Fooooooooooooooooooooo((Type(Baaaaaaaaaaaaaaaaaaar::*)(
    void))&Baaaaaaaaaaaaaaaaaaar::Loooooooooooooooooooooooooooooong);

20

Fooooooooooooooooooooo(
    (Type(Baaaaaaaaaaaaaaaaaaar::*)(void)) &
    Baaaaaaaaaaaaaaaaaaar::Loooooooooooooooooooooooooooooong);
