The first 4 bytes 0xC5 0xFB 0x10 0x0 are "vmovsd (%rax),%xmm0" which uses AVX encoding. This should be recognized in valgrind-3.8.0 which might be released in a couple months. In the meantime, try valgrind-svn; see http://valgrind.org/downloads/repository.html -- ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
