Coredump is about 124MB and I am copying the backtrace of the coredump,
see below. Unfortunately, the sessiond is stripped and no debugging
info, so not able to see the the call stack that lead to the dump. guess
I need to build the lttng with debugging info and to get the symbol and
informed backtrace.
From the log itself, it is asserted aat > > DBG1 -

Hi Yonghong,
thanks for the additional information. Would you be willing and able to
share a coredump and/or backtrace of the crash?
I was still unable to reproduce the issue using the commands you
provided, but am interested in understanding what is happening here.
Are there any configuration options other than LTTNG_UST_DEBUG=1 set in
your environment?
Are you using urcu/lttng from packages (if so, which repo), or built
from source?
The test case I am using now:
```
# As root
$ lttng-sessiond -b
# As a non-root user which is not a member of the tracing group
$ export LTTNG_UST_DEBUG=1
$ lttng-relayd -v -b
$ lttng-sessiond -vvv --verbose-consumer -b
$ lttng create
$ lttng enable-event -u -a
```
thanks,
kienan
P.S. In the future, could you keep the lttng-dev in CC? thanks!
