Good morning,

I'm working on updating cURL to 7.52.1 for Linux From Scratch (I just
updated to 7.52.0 last night!), and am getting errors in the test suite
that I haven't in the past.

I've been getting these errors every 5 tests or so. These are
"Conditional jump or move depends on uninitialised value(s)" errors.
Here is one from test 0587:

Another one from test 1095 (there are several more, but I'm copying them
as they're coming out of my console):

What would you like me to do? Am I doing something wrong, or is this a
resurgence of the same issue that required pushing 7.52.1 out the door?
