[gdal-dev] Slightly-off failing tests on i686

[yosh]

Heya,

I'm currently in the process of updating libgdal for void linux. In the
process, I actually added the test suite to the package, and it seems to be
failing on i686/32bit:

https://github.com/void-linux/void-packages/actions/runs/18897850572/job/53938975118?pr=57703#step:7:7606

in case github actions culls this sooner than expected:

It seems to be ever so slightly off the expected results for numerical
stuff. is this known/expected behavior and/or a supported configuration? Mainly
wondering if it'd be better to skip the tests for i686 or not.

Best,
yosh
