(in /lib/x86_64-linux-gnu/ld-2.24.so) ==1607038== Your program just tried to execute an instruction that Valgrind ==1607038== did not recognise. There are two possible reasons for this. ==1607038== 1. Your program has a bug and erroneously jumped to a non-code ==1607038== location. If you are running Memcheck and you just saw a ==1607038== warning about a bad jump, it's probably your program's fault. ==1607038== 2. The instruction is legitimate but Valgrind doesn't handle it, ==1607038== i.e. it's Valgrind's fault. If you think this is the case or ==1607038== you are not sure, please let us know and we'll try to fix it. ==1607038== Either way, Valgrind will now raise a SIGILL signal which will ==1607038== probably kill your program. ==1607038== ==1607038== Process terminating with default action of signal 4 (SIGILL): dumping core ==1607038== Illegal opcode at address 0x5A33409 ==1607038== at 0x5A33409: rocksdb::AdvancedColumnFamilyOptions::AdvancedColumnFamilyOptions() (in /root/open_source/rocksdb/build/librocksdb.so.6.6.0) ==1607038== by 0x5A33C43: rocksdb::ColumnFamilyOptions::ColumnFamilyOptions() (in /root/open_source/rocksdb/build/librocksdb.so.6.6.0) ==1607038== by 0x5A45CA7: __static_initialization_and_destruction_0(int, int) (in /root/open_source/rocksdb/build/librocksdb.so.6.6.0) ==1607038== by 0x5A484D9: _GLOBAL__sub_I_options_helper.cc (in /root/open_source/rocksdb/build/librocksdb.so.6.6.0) ==1607038== by 0x400F799: call_init.part.0 (dl-init.c:72) ==1607038== by 0x400F8AA: call_init (dl-init.c:30) ==1607038== by 0x400F8AA: _dl_init (dl-init.c:120) ==1607038== by 0x4000C59: ???
