Confirmed, I thought the gimplifier would have to change but it is not that.
If we look at .eh (via -fdump-tree-all-lineno), we see that there is a goto
with the lineno of 10:
[t.c : 7] j = 0;
[t.c : 7] goto <D1243>;
<D1242>:;
[t.c : 8] j.0 = j;
[t.c : 8] D.1249 = (unsigned char) j;
[t.c : 8] block[j.0] = D.1249;
[t.c : 7] j = j + 1;
<D1243>:;
[t.c : 7] if ([t.c : 7] j <= 3) [t.c : 7] goto <D1242>; else [t.c : 7] goto
<D1244>;
<D1244>:;
[t.c : 10] goto <D1246>; /// <--- here
<D1245>:;
[t.c : 11] j.1 = j;
[t.c : 11] D.1251 = (unsigned char) j;
[t.c : 11] block[j.1] = D.1251;
[t.c : 10] j = j + 1;
<D1246>:;
[t.c : 10] if ([t.c : 10] j <= 5) [t.c : 10] goto <D1245>; else [t.c : 10]
goto <D1247>;
<D1247>:;
[t.c : 12] return;
So it is just tree CFG cleanup which is causing this.
