Version: 3.6 SVN (using KDE 1.2) OS: Linux ==17591== Memcheck, a memory error detector ==17591== Copyright (C) 2002-2010, and GNU GPL'd, by Julian Seward et al. ==17591== Using Valgrind-3.6.0.SVN and LibVEX; rerun with -h for copyright info ==17591== Command: ./aterm ==17591== vex x86->IR: unhandled instruction bytes: 0xF3 0xF 0xBD 0x84 ==17591== valgrind: Unrecognised instruction at address 0x465980a. ==17591== Your program just tried to execute an instruction that Valgrind ==17591== did not recognise. There are two possible reasons for this. ==17591== 1. Your program has a bug and erroneously jumped to a non-code ==17591== location. If you are running Memcheck and you just saw a ==17591== warning about a bad jump, it's probably your program's fault. ==17591== 2. The instruction is legitimate but Valgrind doesn't handle it, ==17591== i.e. it's Valgrind's fault. If you think this is the case or ==17591== you are not sure, please let us know and we'll try to fix it. ==17591== Either way, Valgrind will now raise a SIGILL signal which will ==17591== probably kill your program. Reproducible: Always Steps to Reproduce: valgrind <any application> Actual Results: Always fails with the same unhandled instruction error. This problem has been with this AMD Phenom system since it was put together in Jan 2009 it seems to be independent of Linux Kernel,GCC, BinUtils, GLIBC and Valgrind versions which have been updated periodically since that date (see additional information) same problem every time. The machine is generally stable and other debug tools I use work as expected.
