GCC 11+ complains that sym is uninitialized in ctf_symbol_next. It isn't, but it's not quite smart enough to figure that out (it requires domain-specific knowledge of the state of the ctf_next_t iterator over multiple calls). libctf/ * ctf-lookup.c (ctf_symbol_next): Initialize sym to a suitable value for returning if never reset during the function.
