`target_ext_pk` is uninitialised before the loop, and is definitely initialised after the loop *iff* `sanction` isn't NULL. If it is NULL, then `target_ext_pk` is not read. This is verifiable, but not obvious. PVS Studio isn't smart enough to figure that out, so it complains. I consider it a valid complaint, and the new code is clearer: we now call the processing part of the function directly with initialised values instead of relying on that initialisation coinciding with `sanction`s nullity.
