Hello list,

While playing with libgcrypt-1.2.0 I found a small memory leak in
cipher/pubkey.c, function gcry_pk_sign: "gcry_mpi_t * result" is freed
without having its resources freed first. The attached patch seems to fix
the problem. Please have a look at it -  I rather guessed there as I'm new
to libgcrypt land...
