--- Comment #6 from smf.li...@ntlworld.com --- Created attachment 107183 --> https://bugs.kde.org/attachment.cgi?id=107183&action=edit Instrumented guest_amd64_toIR.c I have instrumented guest_amd64_toIR.c and line number 20564 seems to be the source of my issue: ==17761== Memcheck, a memory error detector ==17761== Copyright (C) 2002-2017, and GNU GPL'd, by Julian Seward et al. ==17761== Using Valgrind-3.13.0 and LibVEX; rerun with -h for copyright info ==17761== Command: /bin/bash ==17761== DEBUG Line no 20564 DEBUG Line no 32358 vex amd64->IR: unhandled instruction bytes: 0x8F 0xEA 0x78 0x10 0xD0 0x8 0x4 0x0 0x0 0x89 vex amd64->IR: REX=0 REX.W=0 REX.R=0 REX.X=0 REX.B=0 vex amd64->IR: VEX=0 VEX.L=0 VEX.nVVVV=0x0 ESC=NONE vex amd64->IR: PFX.66=0 PFX.F2=0 PFX.F3=0 ==17761== valgrind: Unrecognised instruction at address 0x401b8b9. ==17761== at 0x401B8B9: get_common_indeces.constprop.1 (in /lib/ld-2.26.so) ==17761== by 0x401C0B3: _dl_sysdep_start (in /lib/ld-2.26.so) ==17761== by 0x4001F17: _dl_start (in /lib/ld-2.26.so) ==17761== by 0x4000F47: ??? (in /lib/ld-2.26.so) ==17761== Your program just tried to execute an instruction that Valgrind ==17761== did not recognise. There are two possible reasons for this. ==17761== 1. Your program has a bug and erroneously jumped to a non-code ==17761== location. If you are running Memcheck and you just saw a ==17761== warning about a bad jump, it's probably your program's fault. ==17761== 2. The instruction is legitimate but Valgrind doesn't handle it, ==17761== i.e. it's Valgrind's fault. If you think this is the case or ==17761== you are not sure, please let us know and we'll try to fix it. ==17761== Either way, Valgrind will now raise a SIGILL signal which will ==17761== probably kill your program. ==17761== ==17761== Process terminating with default action of signal 4 (SIGILL) ==17761== Illegal opcode at address 0x401B8B9 ==17761== at 0x401B8B9: get_common_indeces.constprop.1 (in /lib/ld-2.26.so) ==17761== by 0x401C0B3: _dl_sysdep_start (in /lib/ld-2.26.so) ==17761== by 0x4001F17: _dl_start (in /lib/ld-2.26.so) ==17761== by 0x4000F47: ???
