[Valgrind-users] Unrecognized Instruction in Ubuntu ARM library

[Jim S. <ji...@ji...>]

Running Ubuntu/Mate on a Raspberry Pi 2, I get the following error:

    disInstr(arm): unhandled instruction: 0xF1010200
                      cond=15(0xF) 27:20=16(0x10) 4:4=0 3:0=0(0x0)
    ==2462== valgrind: Unrecognised instruction at address 0x48596f4.
    ==2462==    at 0x48596F4: ??? (in
    /usr/lib/arm-linux-gnueabihf/libarmmem.so)
    ==2462== Your program just tried to execute an instruction that Valgrind
    ==2462== did not recognise.  There are two possible reasons for this.
    ==2462== 1. Your program has a bug and erroneously jumped to a non-code
    ==2462==    location.  If you are running Memcheck and you just saw a
    ==2462==    warning about a bad jump, it's probably your program's
    fault.
    ==2462== 2. The instruction is legitimate but Valgrind doesn't
    handle it,
    ==2462==    i.e. it's Valgrind's fault.  If you think this is the
    case or
    ==2462==    you are not sure, please let us know and we'll try to
    fix it.
    ==2462== Either way, Valgrind will now raise a SIGILL signal which will
    ==2462== probably kill your program.
    ==2462==
    ==2462== Process terminating with default action of signal 4 (SIGILL)
    ==2462==  Illegal opcode at address 0x48596F4
    ==2462==    at 0x48596F4: ??? (in
    /usr/lib/arm-linux-gnueabihf/libarmmem.so)
    ==2462==

Any clue(s) would be appreciated.
