Re: [Test Breakage 2.46.0-rc0] Test t0021.35 fails on NonStop

What is strange is that when running on NonStop using ksh, t0000.1 has never
failed. I think the situation is subtly different from what we are solving.
My take is that there is a difference in the local vs. non-local variable
set semantic, rather than just accepting the keyword. I would propose that
we need a more comprehensive local test to verify the actual expected
semantics rather than just testing the syntax.

It is possible that I may be misreading that first test, but as far
as I can tell, it is testing not just the syntax but tests how the
variables declared "local" behaves and should notice if they are not
localized.  It checks that "local" assignments in try_local_xy does
take effect, and (more importantly) after try_local_xy returns, the
original values are restored.

As I speculated earlier in an earlier message, the breakage you
reported may have to do with interaction between "local" and use of
a subshell, and perhaps we can also check that pattern in the test.

Thanks.
