The problem is in
static void
lto_write_globals (void)
{
tree *vec = lto_global_var_decls->address ();
int len = lto_global_var_decls->length ();
wrapup_global_declarations (vec, len);
emit_debug_global_declarations (vec, len);
vec_free (lto_global_var_decls);
}
LTO no longer maintains its own symbol table and it uses varpool for
variables instead. lto_global_var_decls is almost empty. That
is why debug info on variables is lost.
