Testcase
It's a doubly-reduced testcase (reduced for this PR after having being reduced
for another issue) so it might be borderline, but it should not ICE anyway:
t.cpp: In member function 'k k::l()':
t.cpp:16:18: warning: no return statement in function returning non-void
[-Wreturn-type]
16 | k l() { j.i(); }
| ^
t.cpp: In member function 'a a::i()':
t.cpp:12:3: warning: control reaches end of non-void function [-Wreturn-type]
12 | }
| ^
during GIMPLE pass: switchconv
t.cpp: In member function 'k k::l()':
t.cpp:18:22: internal compiler error: in expand, at
tree-switch-conversion.c:916
18 | void m(k h) { h.l(); }
| ^
