re PR middle-end/45738 (ICE: tree check: expected var_decl, have debug_expr_decl in const_value_known_p, at varpool.c:375)
PR tree-optimization/45738
PR tree-optimization/45741
* expr.c (string_constant): Allow CONST_DECL too;
check that DECL_INITIAL is set.
* varpool.c (const_value_known_p): Only look into VAR_DECL
and CONST_DECL.
* gcc.c-torture/compile/pr45741.c: New.
* gfortran.fortran-torture/compile/pr45738.f90: New.
