Cannot call the same sequence twice from Waldo function

[harrison8989]

For example, if I have a Waldo sequence SeqSendMSG and a Waldo function send_msg defined as

Public Function send_msg(Text msg) {
    SeqSendMSG(msg);
    SeqSendMSG(msg);
}

Calling this function will return the following error, along with a stack trace:

Compiler error: Already had an entry for variable trying to insert into store.

To clarify, the error does not actually occur when the Waldo file is being compiled.

Full code:
Test.wld:

Test
Endpoint Client;
Endpoint Server;

Sequences {
    SeqSendMSG: Client.sendMSG -> Server.receiveMSG;
}

Sequence SeqSendMSG (Text msg) returns Text result
{
    Client.sendMSG {
    }

    Server.receiveMSG {
    }

}

Client
{
    Public Function send_msg(Text msg) {
        SeqSendMSG(msg);
        SeqSendMSG(msg);
    }

}

Server
{
}

Server.py:

from emitted import Server
import sys
sys.path.append("../../../")
from waldo.lib import Waldo
import time

HOSTNAME = '127.0.0.1'
PORT = 9028


Waldo.tcp_accept(Server, HOSTNAME, PORT)

print 'Server is up and running.'

while True:
    pass

Client.py:

from emitted import Client
import sys
sys.path.append("../../../")
from waldo.lib import Waldo

HOSTNAME = '127.0.0.1'
PORT = 9028

client = Waldo.tcp_connect(Client, HOSTNAME, PORT)
client.send_msg('100')
