Simple error case:

/tmp/x.c
char dnet_ntoa();

int main() {
dnet_ntoa()
; return 0; }

gcc -flto /tmp/x.c

Result:
lto1: internal compiler error: in lto_symtab_prevailing_decl, at
lto-symtab.c:644
0x783c63 lto_symtab_prevailing_decl(tree_node*)
    ../../gcc/lto-symtab.c:644
0x500719 lto_fixup_state
    ../../gcc/lto/lto.c:3257

    ../../gcc/lto/lto.c:3490

Should return for: gcc /tmp/x.c
