re PR c++/20721 (crossing of a initialization left undetected on goto)
PR c++/20721
* cp-tree.h (DECL_NONTRIVIALLY_INITIALIZED_P): New macro.
* decl.c (duplicate_decls): Merge it into new declarations.
(decl_jump_unsafe): Use it, rather than DECL_INITIAL.
(cp_finish_decl): Set it, when appropriate.
PR c++/20721
* g++.dg/init/goto2.C: New test.
