--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Actually wait it is enabled:
```
Wjump-misses-init
C ObjC Var(warn_jump_misses_init) Warning LangEnabledby(C ObjC,Wc++-compat)
Warn when a jump misses a variable initialization.
```
But I don't get a warning unless I use the option directly.
Simple example:
```
int f(int a)
{
goto b;
int t = a;
b:
return t;
}
```
