[Long analysis of probable cause of the problem]

Thank you for this. I was suspecting something along these lines,
but I don't yet know my way around the source well enough to figure
out where the problem was coming from.

In the meantime, I hope that some available workarounds for the bug are
clear from this discussion: avoid using multiple constants in a single
compilation unit where one is 0.0 and another is -0.0, or, if you really
can't avoid that, perhaps use compiler.compile to explicitly build the
bytecode you need.

Yup: the workaround seems to be as simple as replacing all occurrences
of -0.0 with -(0.0). I'm embarrassed that I didn't figure this out
sooner.

x, y = -(0.0), 0.0
x, y
(-0.0, 0.0)
