[Stackless] crash on exit while daemon thread is still running

[Y. Sapir]

I'm running the 3.3-slp branch on Ubuntu 12.10. The script below gives
me a segfault. Is this a known problem?


import threading
import stackless

chan = stackless.channel()

def producer():
    while True:
        chan.send(1)

def consumer():
    while True:
        chan.receive()

def run_tasklet(func, iterations):
    stackless.tasklet(func)()
    for i in range(iterations):
        stackless.run()

thread = threading.Thread(
    target=run_tasklet,
    args=(producer, 1000000),
    daemon=True)
thread.start()

run_tasklet(consumer, 10)


And here's the stacktrace I get from gdb:

#0  0xb7e43850 in slp_kill_tasks_with_stacks (ts=ts at entry=0x0) at

Thanks.
