--- Comment #4 from Mikhail Maltsev <miyuki at gcc dot gnu.org> ---
IMHO, this is not just a documentation bug (no one reads it anyway ;)). A
better solution (from the QOI point of view) would be to diagnose each call to
exec* and fork, when both -fprofile-arcs (implied by --coverage) and
-std=c99/c11 are used.
