I get a GL_INVALID_OPERATION when using `glBegin() .. glEnd()` with SDL_GL_CONTEXT_PROFILE_MASK.  The problem occurs with Version 3.2 and version 4.1 on my machine.


Note: OS is actually Mac OS 10.14 (it is not in the list)

I think it is a Mac OS issue - but maybe there is some kind of workaround?  I would really like to use version 4.1.

Code to reproduce (minimal exmaple).
