* tree-eh.c (decide_copy_try_finally): At -O0, return true
even when ndests is not 1, if there are only gimple_clobber_p
(or debug) stmts in the finally sequence.
* tree-inline.c (estimate_num_insns): Return 0 for gimple_clobber_p
stmts.
* gcc.dg/pr51644.c: New test.
* g++.dg/warn/Wreturn-4.C: New test.
