--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
I can't easily bisect when this started but bet with
r12-5412-g458d2c689963d8461d84670a3d8988cd6ecbfd81
or later.
Not sure if this should be P1 because it is ice-checking only, in release
compilers flag_checking defaults to 0 and so it isn't done unless -fchecking is
used.
