`read()` not working with cx chains

[0pcom]

modification were made to the bc-counter example as follows:

package bc

var counter i32
var word str

func incCounter() {
	if counter > 1 {
		printf("previous input: %s\n", word)
	}
	printf("type anything:\n")
	word  = read()
	printf("\nyou typed: %s\n", word)
	counter++
	printf("Blockchain counter: %d\n", counter)
}

package main

func main() {

The local cx environment was set up / reset ; the chain was initialized against the modified example; cx-tracker, publisher, and peer were running. In the output, as you can see the first transaction incremented the counter to 1 and prompted for input which should have been read back but wasn't.

The second transaction caused error. When this was tested on the previous (original) implementation of cx-chains I believe the peer node would crash at this point, but it did not during the current test, so that is a step in the right direction. The run, as described above:

export CXCHAIN_GEN_SK=$(cxchain-cli key -in skycoin.genesis_keys.json -field "seckey")
 export CXCHAIN_HASH=$(cxchain-cli genesis -in skycoin.chain_spec.json)
