* match.c (recursive_stmt_fcn): Add checks that symtree exists
for the expression to weed out inline intrinsic functions and
parameters.
PR fortran/24409
* module.c (mio_symtree_ref): Correct the patch of 0923 so that
a symbol is not substituted for by a the symbol for the module
itself and to prevent the promotion of a formal argument.
