I see the following error:
(etrace-0.82-b2-dev at local) traces add foo
[*] Unable to add func at 0x08048394 into trace
<-----------------------
[*] Added function foo successfully into trace global
Can you profile-warn for the traces command too ?
Also, make sure you use the trace commands in the same way as in the example
of the testsuite (testsuite/tracing)
