These don't look like messages from Valgrind. Is this from the
system console?

The opcode 0x10000484 is the prototypical Altivec instruction
(vor 0,0,0) that Valgrind uses to check if your system supports
Altivec instructions.

Most likely you can ignore this, Valgrind is expecting either
a SIGILL (or not), and should get the SIGILL in this case.
