Fortran: avoid NULL pointer dereferences
CLASS(), PARAMETER is not yet properly implemented in gfortran. Using it
in declarations could lead to subsequent NULL pointer dereferences during
checking or simplification of expressions involving those CLASS variables.
gcc/fortran/ChangeLog:
PR fortran/103137
PR fortran/103138
* check.c (gfc_check_shape): Avoid NULL pointer dereference on
missing ref.
* simplify.c (gfc_simplify_cshift): Avoid NULL pointer dereference
when shape not set.
(gfc_simplify_transpose): Likewise.
