==21224==    at 0x84B2166: ??? (in /usr/bin/skype) 
==21224== Your program just tried to execute an instruction that Valgrind 
==21224== did not recognise.  There are two possible reasons for this. 
==21224== 1. Your program has a bug and erroneously jumped to a non-code 
==21224==    location.  If you are running Memcheck and you just saw a 
==21224==    warning about a bad jump, it's probably your program's fault. 
==21224== 2. The instruction is legitimate but Valgrind doesn't handle it, 
==21224==    i.e. it's Valgrind's fault.  If you think this is the case or 
==21224==    you are not sure, please let us know and we'll try to fix it. 
==21224== Either way, Valgrind will now raise a SIGILL signal which will 
==21224== probably kill your program. 
==21224== 
==21224== Process terminating with default action of signal 4 (SIGILL)
