The entire code is available from here:

http://git.savannah.gnu.org/cgit/libidn.git/tree/gltests/test-open.h
http://git.savannah.gnu.org/cgit/libidn.git/tree/gltests/test-open.c

It is the second assertion that is failing, which suggests the program
was able to read data out of /dev/null on the build host.

I think your program does basically the same thing as the self-test.  So
the question is if it works in a build environment on the caballero
buildd.  Maybe the build environment sets up a non-standard /dev/null?
