Just to check - did you really compile your code with frame pointers? 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.

I don't specifically use -fno-omit-frame-pointer, no. But the normal stack
unwinding works just fine with mainline perf nevertheless; is this expected?
