Yes.  (I've mentioned this a number of times.)

What issues?

If you're referring to the fact that a break statement can occur only
within a loop or switch, I don't see the problem.  A break statement
that's not within a loop or switch is a constraint violation, not a
syntax error.  I've never heard of a C compiler having any difficulty
diagnosing it correctly.

If you're referring to the fact that break can apply either to a loop or
to a switch, that's a potential source of confusion, but it shouldn't be
a problem once you're aware of it.
