There are two possible reasons for this. ==30104== 1. Your program has a bug and erroneously jumped to a non-code ==30104== location. If you are running Memcheck and you just saw a ==30104== warning about a bad jump, it's probably your program's fault. ==30104== 2. The instruction is legitimate but Valgrind doesn't handle it, ==30104== i.e. it's Valgrind's fault. If you think this is the case or ==30104== you are not sure, please let us know and we'll try to fix it. ==30104== Either way, Valgrind will now raise a SIGILL signal which will ==30104== probably kill your program. ==30104== ==30104== Process terminating with default action of signal 4 (SIGILL) ==30104== Illegal opcode at address 0x111D28 ==30104== at 0x111D28: crandom_generate (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30104== by 0x10B003: goldilocks_keygen (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30104== by 0x10A8B2: crypto_dh_ed448goldilocks_64_keypair (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30104== by 0x1096F8: test (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30104== by 0x1090D4: main (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30104== ==30104== HEAP SUMMARY: ==30104== in use at exit: 4,800 bytes in 12 blocks ==30104== total heap usage: 22 allocs, 10 frees, 30,008 bytes allocated ==30104== ==30104== LEAK SUMMARY: ==30104== definitely lost: 0 bytes in 0 blocks ==30104== indirectly lost: 0 bytes in 0 blocks ==30104== possibly lost: 4,800 bytes in 12 blocks ==30104== still reachable: 0 bytes in 0 blocks ==30104== suppressed: 0 bytes in 0 blocks ==30104== Rerun with --leak-check=full to see details of leaked memory ==30104== ==30104== For lists of detected and suppressed errors, rerun with: -s ==30104== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
