When I built with -O0 the backtrace changed.

Looking at the way genrand.c is coded it should be using the read_data() function
from sys_rw_data.c. When I debug the read_data call it is calling it ends up in a
read_data() function from a third-party library:

The libtspi.so.1 library is from 'trousers-lib'.
Are any of you compiling kodi with the 'trousers' library installed?
Thanks,
