There are two possible reasons for this. ==30012== 1. Your program has a bug and erroneously jumped to a non-code ==30012== location. If you are running Memcheck and you just saw a ==30012== warning about a bad jump, it's probably your program's fault. ==30012== 2. The instruction is legitimate but Valgrind doesn't handle it, ==30012== i.e. it's Valgrind's fault. If you think this is the case or ==30012== you are not sure, please let us know and we'll try to fix it. ==30012== Either way, Valgrind will now raise a SIGILL signal which will ==30012== probably kill your program. ==30012== ==30012== Process terminating with default action of signal 4 (SIGILL) ==30012== Illegal opcode at address 0x10F294 ==30012== at 0x10F294: crandom_generate (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30012== by 0x10A97B: goldilocks_keygen (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30012== by 0x10A2E6: crypto_dh_ed448goldilocks_64_keypair (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30012== by 0x109592: test (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30012== by 0x108FC4: main (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==30012== ==30012== HEAP SUMMARY: ==30012== in use at exit: 4,800 bytes in 12 blocks ==30012== total heap usage: 22 allocs, 10 frees, 30,008 bytes allocated ==30012== ==30012== LEAK SUMMARY: ==30012== definitely lost: 0 bytes in 0 blocks ==30012== indirectly lost: 0 bytes in 0 blocks ==30012== possibly lost: 4,800 bytes in 12 blocks ==30012== still reachable: 0 bytes in 0 blocks ==30012== suppressed: 0 bytes in 0 blocks ==30012== Rerun with --leak-check=full to see details of leaked memory ==30012== ==30012== For lists of detected and suppressed errors, rerun with: -s ==30012== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
