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. > This program works on ia64 -- it completes with no output, and exits > 0. 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? Thanks, /Simon -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
