Comment (by teor):

 Code review using clang  (Xcode 6.4 (6E35b) Apple LLVM version 6.1.0
 (clang-602.0.53)  (based on LLVM 3.6.0svn)) on OS X 10.10.4.

 Build & static analysis:

 clang would prefer iters to be a `#define`
 {{{
 test_crypto_ed25519_fuzz_donna(void *arg)
 {
   const int iters = 1024;
   uint8_t msg[iters];
 }}}
 `tor/src/test/test_crypto.c:1643:15: Variable length array folded to
 constant array as an extension`

 Other than that, there are no build or static analyzer complaints from
 clang.
