SUMMARY
Could not start binary under valgrind and got the "Unrecognised instruction"

==7844== Your program just tried to execute an instruction that Valgrind
==7844== did not recognise. There are two possible reasons for this.
==7844== 1. Your program has a bug and erroneously jumped to a non-code
==7844== location. If you are running Memcheck and you just saw a
==7844== warning about a bad jump, it's probably your program's fault.
==7844== 2. The instruction is legitimate but Valgrind doesn't handle it,
==7844== i.e. it's Valgrind's fault. If you think this is the case or
==7844== you are not sure, please let us know and we'll try to fix it.
==7844== Either way, Valgrind will now raise a SIGILL signal which will
==7844== probably kill your program.
==7844==
==7844== Process terminating with default action of signal 4 (SIGILL)
==7844== Illegal opcode at address 0x7BF277

ADDITIONAL INFORMATION
The binary can start successfully without valgrind. I tried to use latest
valgrind version 3.21 but facing the same issue
