There are two possible reasons for this. ==28208== 1. Your program has a bug and erroneously jumped to a non-code ==28208== location. If you are running Memcheck and you just saw a ==28208== warning about a bad jump, it's probably your program's fault. ==28208== 2. The instruction is legitimate but Valgrind doesn't handle it, ==28208== i.e. it's Valgrind's fault. If you think this is the case or ==28208== you are not sure, please let us know and we'll try to fix it. ==28208== Either way, Valgrind will now raise a SIGILL signal which will ==28208== probably kill your program. ==28208== ==28208== Process terminating with default action of signal 4 (SIGILL) ==28208== Illegal opcode at address 0x40C2B2 ==28208== at 0x40C2B2: crandom_generate (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==28208== by 0x402DC6: goldilocks_keygen (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==28208== by 0x402AC4: crypto_dh_ed448goldilocks_64_keypair (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==28208== by 0x401356: test (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==28208== by 0x402680: main (in /home/moritz/Uni/2015-2016/research-internship/letstrythisagain/supercop-20181113/bench/venus/work/compile/try) ==28208== ==28208== HEAP SUMMARY: ==28208== in use at exit: 4,800 bytes in 12 blocks ==28208== total heap usage: 22 allocs, 10 frees, 30,008 bytes allocated ==28208== ==28208== LEAK SUMMARY: ==28208== definitely lost: 0 bytes in 0 blocks ==28208== indirectly lost: 0 bytes in 0 blocks ==28208== possibly lost: 4,800 bytes in 12 blocks ==28208== still reachable: 0 bytes in 0 blocks ==28208== suppressed: 0 bytes in 0 blocks ==28208== Rerun with --leak-check=full to see details of leaked memory ==28208== ==28208== For lists of detected and suppressed errors, rerun with: -s ==28208== ERROR SUMMARY: 0 errors from 0 contexts (suppressed: 0 from 0)
