Hi, I'm running sample app in lttng-ust/doc/examples/easy-ust and it is crashing with following traceback. (infact all the instrumented app's crash)
I have attached complete lttng logs. I'm using 2.6.0 Can you please let me know if i'm missing anything here? aneeli@aneeli-desktop: easy-ust$ ./sample sample: lttng-ust-abi.c:436: lttng_abi_map_channel: Assertion `chan' failed.
