There are two possible reasons for this. ==25593== 1. Your program has a bug and erroneously jumped to a non-code ==25593== location. If you are running Memcheck and you just saw a ==25593== warning about a bad jump, it's probably your program's fault. ==25593== 2. The instruction is legitimate but Valgrind doesn't handle it, ==25593== i.e. it's Valgrind's fault. If you think this is the case or ==25593== you are not sure, please let us know and we'll try to fix it. ==25593== Either way, Valgrind will now raise a SIGILL signal which will ==25593== probably kill your program. ==25593== ==25593== Process terminating with default action of signal 4 (SIGILL) ==25593== Illegal opcode at address 0x40CA42 ==25593== at 0x40CA42: crandom_generate (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==25593== by 0x4030B6: goldilocks_keygen (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==25593== by 0x402CE4: crypto_sign_ed448goldilocks_arm32_keypair (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==25593== by 0x4013B6: test (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==25593== by 0x4028A0: main (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==25593== ==25593== HEAP SUMMARY: ==25593== in use at exit: 44,640 bytes in 10 blocks ==25593== total heap usage: 20 allocs, 10 frees, 67,544 bytes allocated ==25593== ==25593== LEAK SUMMARY: ==25593== definitely lost: 0 bytes in 0 blocks ==25593== indirectly lost: 0 bytes in 0 blocks ==25593== possibly lost: 44,640 bytes in 10 blocks ==25593== still reachable: 0 bytes in 0 blocks ==25593== suppressed: 0 bytes in 0 blocks ==25593== Rerun with --leak-check=full to see details of leaked memory ==25593== ==25593== For lists of detected and suppressed errors, rerun with: -s ==25593== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
