Hello
If you want to debug and fixe the application, you can follow these steps :
- compile the application in debug mode
- activate cores :
$ ulimit -c unlimited
- run the application with prctl :
$ prctl --unaligned=signal <cmd>
[...]
Bus error (core dumped)
- analyse the core dump with gdb
If you only want to disable unaligned message, you can run the
application with
"prctl --unaligned=silent "
