By default, that is not the case, and the above will try to do frame pointer unwinding which will then fail. Put differently - do you any stack frames at all? Can you try `perf record --call-graph dwarf` instead? Of course, make sure you compile your code with `-g -O2` or similar. -- Milian Wolff | milian.wolff@kdab.com | Software Engineer KDAB (Deutschland) GmbH&Co KG, a KDAB Group company Tel:
