Linux di 3.12.9-2-ARCH #1 SMP PREEMPT Fri Jan 31 10:22:54 CET 2014 x86_64 GNU/Linux turnserver-3.2.2.5 archlinux

I don`t know could that produce a bug in a working app, but at least it will be usefull to put warnings about compilation flags to the docs.

Thanks for reporting.

I am trying to reproduce the problem on exactly the same system (archlinux 3.12.9-2 SMP with all the same libraries, and I use exactly the same command lines) and I failed to see any problem. The only difference is that I used version 3.2.2.6 (pre-release) but that must make no difference.

There are several very strange things:

1) The line "RFC 5769 IPv6 encoding result: success" means that the program completed successfully - the next instruction is just "return 0" from the main function - so how come there may be a problem AFTER that ?

2) If you are running it on a x86_64 system, then what are you trying to achieve with options "-m64 -march=native" ?

3) Is that possible that you ran the configuration and the compilation with option -m32, then you did not run "make clean" and then you tried immediately "-m64" ? That would explain the problem.

4) The Makefile was written for sequential execution - it was not designed for parallel tasks and it was not tested as such. May be "make -j4" is the problem in your case.

So, I am sking you to:

1) Do "make clean" before the build process. 2) Remove -j4 option. 3) If the problem still exist, could you please run it in the debugger ? Add option -g and run the program bin/turnutils_rfc5769check in gdb.

Thanks Oleg

Another thing that I suspect is that the stack protector may be somehow is responsible for the message.

I'll fix it if I'll have information how to reproduce it reliably.

Cant reproduce this morning. I think that behaviour was caused by the kernel updated in previous step without rebooting. Im sorry. You can close the bug.
