You do know what ldd does, don't you? It does run the binary you've just created. No wonder it coredumps, because it contains garbage. If you want to take a look on binary, use objdump (in particular, "objdump -p" when seeking for libraries - note, this will show only libraries used by the file you're investigating only, not every library that's loaded before main() being called), and not ldd. So just run "objdump -x a.out" on the binary you've created, and you'll see it's actually empty. Regarding ld... it just fails to fail properly when it encounters zero-size input. You'll get the same result with, e.g., /dev/null. Could you construct a patch for this? -- WBR, Vadim Zhukov
