--- Comment #8 from Martin Sebor <msebor at gcc dot gnu.org> ---
GCC 11 (and prior) diagnose both functions in comment #0, I suspect as a result
of r156156:
pr49754.c: In function ‘foo’:
pr49754.c:2:38: warning: ‘x’ is used uninitialized [-Wuninitialized]
2 | struct i foo () { struct i x; return x; }
| ^
pr49754.c:2:28: note: ‘x’ declared here
2 | struct i foo () { struct i x; return x; }
| ^
pr49754.c: In function ‘bar’:
pr49754.c:3:28: warning: ‘y’ is used uninitialized [-Wuninitialized]
3 | int bar () { int y; return +y; }
| ^~
Returning larger aggregates started to be diagnosed in r245840. Passing
structs to other functions by value still isn't diagnosed. It used to be, but
it stopped sometime between r143699 and r143725.
See pr95848 that tracks the problem with pass-by-value.
