The following config:

./configure --with-liboqs --enable-all --disable-psk --enable-intelasm --enable-aesni --enable-sp-math-all --enable-sp-asm CFLAGS="-O3"

Yeilds the following erorr:

src/internal.c: In function ‘DoServerKeyExchange’:
src/internal.c:24487:28: error: ‘sigAlgo’ may be used uninitialized in this function [-Werror=maybe-uninitialized]

      |                            ^

This fixes it.
