Valgrind Issue : illegal opcode memcpy in /lib/ld-2.8.so
 

Hi LQ,

I am running Valgrind on PowerPC target machine. I get the following error

What should i do to solve this issue.

Please note the executable 'temp' used in this case is a simple c program executable.

Thanks,

==2850== valgrind: Unrecognised instruction at address 0x4019510.
==2850== Your program just tried to execute an instruction that Valgrind
==2850== did not recognise. There are two possible reasons for this.
==2850== 1. Your program has a bug and erroneously jumped to a non-code
==2850== location. If you are running Memcheck and you just saw a
==2850== warning about a bad jump, it's probably your program's fault.
==2850== 2. The instruction is legitimate but Valgrind doesn't handle it,
==2850== i.e. it's Valgrind's fault. If you think this is the case or
==2850== you are not sure, please let us know and we'll try to fix it.
==2850== Either way, Valgrind will now raise a SIGILL signal which will
==2850== probably kill your program.
