count(*) in binary mode returns 0

I have an implementation of binary format communication that is working quite well but it is failing inexplicably on returning valid results for the aggregate function count. It returns a correct result for instance for the aggregate function max. 

Here is some debug information to illustrate that I have debugged the host order conversions and what have you in implementing this binary format. As you can see, it is simply returning 0.

s:select count(*) from "User" where ("email" = $1)
valsl 1
val_str:t@xxxxx len:7
result received
free_iter_pre
alloc_result pre
fname: count
nfields: 1
