Yes, it's alright.

These errors are all due to the conservative garbage collector scanning
uninitialized memory, which is to be expected and should not cause any
problems.

Strictly speaking, referencing uninitialized memory does not conform to
the C standard.  However, the conservative garbage collector was never
intended to be strictly conforming code.
