#3423: Undefined behavior in crypto/cast/c_enc.c

[starlight.2015q2 at binnacle.cx]

Hello,

FYI using gcc 4.9.2 on x86_64 AMD

after Configure added

   -flto
   -g
   -fstack-protector-all --param ssp-buffer-size=1
   -fsanitize=address
   -fsanitize=undefined
   -fasynchronous-unwind-tables
   -DOPENSSL_NO_BUF_FREELIST

and 'make test' fails with old bug marked "resolved"

  3423: Undefined behavior in crypto/cast/c_enc.c



started with

./Configure \
    linux-x86_64 \
    enable-ec_nistp_64_gcc_128 \
    shared \
    threads \
    zlib \
    no-ssl2 \
