That's the expected output. The interesting part is in the *.fail files ;)
Could you diff -u the .out file versus the .fail file?

I've seen some subtle floating point failures not unlike the ones on alpha on
mips-irix (where class library compilation fails with the same message
regarding MIN_VALUE of Float like it used to on alphas before -mieee) and maybe
on arm-linux as well. I've though I could blame it on the strtod
implementations, but alpha seems to show that there might be something else

cool, I'm looking forward to the patch.

I'm sort of puzzled about these. Especially since name and type are pointers to
Utf8constants and Classes. Maybe the code just needs a clean up ;)
