Your were right, after I rebuilt glibc problem went away. Seems that to build recent libc I have to use recent gcc. Thank you for pushing me to the right direction. All tests pass fine now.

Thanks for the bug report.

Given that the code works on other platforms, I would suspect a compiler problem. Can you try recompiling without optimisation?

If that does not work, perhaps you could look at the actual values in check_full() in sum/test.c.

Unfortunately I have no way test directly on any MIPS machine myself.
