--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
Sorry for the late reply.

I think you are right that initializing these two small (6 ints) arrays at =
the
start of the function is fine if it helps the compiler.

I haven't been able to reproduce the compiler warning myself though.
My proposed patch would be:

diff --git a/compress.c b/compress.c
index 5dfa002..c825c78 100644
--- a/compress.c
+++ b/compress.c
@@ -253,8 +253,8 @@ void sendMTFValues ( EState* s )
    --*/


-   UInt16 cost[BZ_N_GROUPS];
-   Int32  fave[BZ_N_GROUPS];
+   UInt16 cost[BZ_N_GROUPS] =3D { 0 };
+   Int32  fave[BZ_N_GROUPS] =3D { 0 };

    UInt16* mtfv =3D s->mtfv;


{ 0 } initializes the whole array with zero, so we don't have to know the e=
xact
number of elements.

Does the above work for you?
