--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> ---
Confirmed. Alex - how do we distinguish before/after sequence point here
when breaking on line 7? Is this a consumer issue? As you can see the
actual breakpoint is on the implicit return, but in final the simple-return
pattern is associated with line 8... (but still covered by the line 7
DEBUG BEGIN_STMT it seems).
b ()

<bb 2> [local count: 1073741824]:

[t.c:5:5] # DEBUG BEGIN_STMT

[t.c:8:1] return;
