More precise back-trace:

Where debug_rtx(result):
(reg/v:DI 157 [ path ])
if I go up in BT:
#11 0x00000000103505a4 in expand_call_stmt (stmt=0x3fffafcc5bb0) at
../../gcc/cfgexpand.c:2321
2321 expand_assignment (lhs, exp, false);
(gdb) call debug_gimple_stmt(stmt)
# .MEM_2 = VDEF <.MEM_1(D)>
<retval> = path_filepath.FromSlash.localalias.1 (path); [return slot
optimization] [tail call]
I think it would be duplicate of PR63587, where we expand thunk and RESULT_DECL
is given as argument for add_local_decl.
Thanks,
Martin
