I'll see if I can get it patched up.

One issue is simple:

diff --git a/src/app-layer-detect-proto.c b/src/app-layer-detect-proto.c
index fb25b5b..541fa24 100644

     if (alpd_ctx.spm_global_thread_ctx == NULL) {
         SCLogError(SC_ERR_FATAL, "Unable to alloc SpmGlobalThreadCtx.");

But it seems it requires some more work to actually work correctly.

3.1.1 will contain the above fix, but other fixes may be needed. If anyone has interest in helping to address those, please step forward.
