This looks suspicious since these are in call to already type/rank specific runtime library function _gfortran_reshape_r8(). Sadly the lto-dump(1) tool is unable to dump type information about called functions arguments. Looking at gcc/fortran/intrinsic.c it is seen that -fdefault-real-* -fdefault-integer-* options have same effect as -freal-M-real-N or -finteger-M-integer-N options. This does not look intentional as this breaks use of certain (more archaic forms) intrinsics with variables and numeric constants that have explicit kinds.
