I think they most likely cannot hurt...

I use them in rare cases for error handling, similar to the linux
kernel... have X initializations, if one of them fails jump to the
same "initfailed:" point in the same function. That is the only
usecase I have ever considered for goto.

The big question is why did the gcc-warning script failed.

billions of percent in a tiny fraction of a second. Of course, that
was before the present government."
