Re: [Valgrind-users] Valgrind trunk on Mac

[Jacob G. <ja...@ad...>]

Hi Julian,

I just synced to r12813 and I'm still getting an error when running an
arbitrary WebKey layout test under Valgrind (see output below).

Nikolas - can you give this a try and see if you get the same results?

==1322== Your program just tried to execute an instruction that Valgrind
==1322== did not recognise.  There are two possible reasons for this.
==1322== 1. Your program has a bug and erroneously jumped to a non-code
==1322==    location.  If you are running Memcheck and you just saw a
==1322==    warning about a bad jump, it's probably your program's fault.
==1322== 2. The instruction is legitimate but Valgrind doesn't handle it,
==1322==    i.e. it's Valgrind's fault.  If you think this is the case or
==1322==    you are not sure, please let us know and we'll try to fix it.
==1322== Either way, Valgrind will now raise a SIGILL signal which will
==1322== probably kill your program.
