This problem goes away when I upgrade to jasper-4.0.

Sigh.

We should therefore make the CMake build require jasper-4.0 for MacOS. But is this a problem that just happens on MacOS, or one that also happens on Linux but is not detected by address santizer?

@DusanJovic-NOAA do you know anything about why Jasper versions earlier than 4.0 no longer work on macos-latest?

[DusanJovic-NOAA]

I don't know.
