There are two possible reasons for this. ==27158== 1. Your program has a bug and erroneously jumped to a non-code ==27158== location. If you are running Memcheck and you just saw a ==27158== warning about a bad jump, it's probably your program's fault. ==27158== 2. The instruction is legitimate but Valgrind doesn't handle it, ==27158== i.e. it's Valgrind's fault. If you think this is the case or ==27158== you are not sure, please let us know and we'll try to fix it. ==27158== Either way, Valgrind will now raise a SIGILL signal which will ==27158== probably kill your program. ==27158== ==27158== Process terminating with default action of signal 4 (SIGILL) ==27158== Illegal opcode at address 0x112D90 ==27158== at 0x112D90: crandom_generate (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==27158== by 0x10BA9A: goldilocks_keygen (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==27158== by 0x10B2C2: crypto_sign_ed448goldilocks_amd64_keypair (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==27158== by 0x1096B3: test (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==27158== by 0x1090C4: main (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==27158== ==27158== HEAP SUMMARY: ==27158== in use at exit: 44,640 bytes in 10 blocks ==27158== total heap usage: 20 allocs, 10 frees, 69,848 bytes allocated ==27158== ==27158== LEAK SUMMARY: ==27158== definitely lost: 0 bytes in 0 blocks ==27158== indirectly lost: 0 bytes in 0 blocks ==27158== possibly lost: 44,640 bytes in 10 blocks ==27158== still reachable: 0 bytes in 0 blocks ==27158== suppressed: 0 bytes in 0 blocks ==27158== Rerun with --leak-check=full to see details of leaked memory ==27158== ==27158== For lists of detected and suppressed errors, rerun with: -s ==27158== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
