This is more of a meta-comment. I'm not famliar enough with this
particular interface to comment on your analysis. If you believe your
analysis correct please try to work on the patch. After you have a
patch you should run the testsuite on i686 and sh, comparing the
results before and after your patch. All of this information gives the
reader more confidence in your analysis, and may sway a reader to do
their own independant verification.

Remember that the glibc community is made up of volunteers. These
volunteers make decisions about how best to spend their time. It's
difficult to allocate time to a an idea, that even the poster is
unsure, is correct.

Cheers,
Carlos.
