re PR c/43381 (infinite loop in gcc.dg/parm-impl-decl-1.c with -g)
PR c/43381
* c-decl.c (get_parm_info): Assert that decl going in OTHERS has a
nested binding iff it is a FUNCTION_DECL.
(store_parm_decls_newstyle): Pass nested=true to bind for
FUNCTION_DECLs amongst parameters.
testsuite:
* gcc.dg/parm-impl-decl-3.c: New test.
