Memory bug: Double free or corruption

[rs22]

Running the scils_example_local multiple times in succession yields a double free or corruption (out) crash on the client side.

Script to reproduce (assuming code is compiled using CMake in build):

#! /bin/bash -e

cd build/bin/exe/examples

function run_scils() {
    MODE=$1

    # Set up fifo to be able to pass in commands
    rm -f /tmp/$MODE-input
    mkfifo /tmp/$MODE-input
    # Keep the fifo open
    cat > /tmp/$MODE-input &

    tail -f /tmp/$MODE-input | ./scils_example_local $MODE &
}

run_scils s
SERVER=$!

# Listen
echo "" > /tmp/s-input
sleep 1

while ps -p $SERVER > /dev/null; do
    echo "Connecting to server..."

    run_scils c
    CLIENT=$!

    # Connect
    echo "" > /tmp/c-input
    sleep 1

    # Disconnect
    echo "" > /tmp/c-input
    wait $CLIENT || break
    sleep 1
done

kill $SERVER
