hi, I recall there was some issue wrt threading and intel_pt, which we either need to fixed or we need to disable threads for it
[root@krava perf]# ./perf record -e intel_pt// --threads=cpu ^C[ perf record: Woken up 121 times to write data ] Warning: AUX data lost 95 times out of 206!
[ perf record: Captured and wrote 211.364 MB perf.data ]
[root@krava perf]# ./perf script Segmentation fault (core dumped)
the fix should already be in the perf/record_threads branch,
