[Valgrind-users] Unrecognised instruction at address

[Vivek S. <s.v...@gm...>]

Hi All,

This is my first post at Valgrind.

I am using valgrind memory check against a C++ client appliction build
using CEF and Qt. I have build my client applicaiton using -O0 -O1 -g
compiler flags. But the external libraries that I use, are not built using
these flags.

Below is the output I get stating "unhandled instruction".
Is this because of depending on libraries that are not build with the above
flags?

Can you please suggest some pointers on going around with this error.

==31825== Your program just tried to execute an instruction that Valgrind
==31825== did not recognise.  There are two possible reasons for this.
==31825== 1. Your program has a bug and erroneously jumped to a non-code
==31825==    location.  If you are running Memcheck and you just saw a
==31825==    warning about a bad jump, it's probably your program's fault.
==31825== 2. The instruction is legitimate but Valgrind doesn't handle it,
==31825==    i.e. it's Valgrind's fault.  If you think this is the case or
==31825==    you are not sure, please let us know and we'll try to fix it.
==31825== Either way, Valgrind will now raise a SIGILL signal which will
==31825== probably kill your program.
