Thanks Carsten and Dago, with the BUILD64_ONLY = 1 I was able to it to
build just on 64 and the same test still failed, so it's not a 32bit
vs 64bit dependent thing...

Nice, thanks for the info. This is good to know.

Ok.

Thanks for the verification.

Bingo, it seems not! When I run the test manually (after up'ing the
filehandles) it returns without error, doesn't core and a returns a
return code of 0. Then when I bring the filehandles back down to 256
and run the test again it cores and errors out as it does during the
build run tests. Now to figure out why the ulimit settings in my
.bash_profile don't affect it when going through the build process.
Does the build process use 'sh' I wonder...

Will report back when I've found the culprit. Thanks for the very useful info.
