[BUG] t0410 2.20.1 fails on NonStop NSX platform

This is a bit of a head-scratcher. There are two NonStop platforms, which behave essentially the same way. One, NSE, uses ia64, while NSX uses x64. There are subtle differences in ksh and bash for the platforms based on what is released when. The NSE platform has no problem running t0410 in Jenkins. However, NSX fails in a few spots:

This is at 2.20.1. Our last port on this platform variant was 2.16.1, where there were no unexplained issues.

I am suspecting that the problem is shell related, but I'm just not sure what the test is supposed to do here. There are 9 other failures that appear related, with the No such file or directory condition. If I add the -f flag to rm in delete_object(), all t0410 tests pass except the last (22), but I don't think that meets the intent of test itself. I wonder whether one of the authors of the test might chime in on this.

The first, subtest 12 results in:
