Bug report

Required Info:

Steps to reproduce issue

Use Nav2 to navigate turtlebot3 in gazebo.

We see crashes when we test Nav2, and it seems some errors are caused by the middleware.

@zouyonghao thanks for registering issue.

Could you provide the reproducible procedure about 'test Nav2'? sorry i do not know very much about that, but I would like to try with mainline.

zouyonghao commented 3 years ago

Hi @fujitatomoya I just use Nav2 with the tutorial here , and this issue only happened one or two times and can not be reproduced stably. Maybe it's a data race related issue in librcl according to the asan trace?
