Bug#1071752: satpy: arm64 fails netCDF4 tests with scipy 1.12

[Drew Parsons]

Source: satpy
Version: 0.48.0-2
Severity: normal

scipy 1.12 is triggering test failure on arm64

https://ci.debian.net/packages/s/satpy/unstable/arm64/46960923/
https://ci.debian.net/packages/s/satpy/unstable/arm64/

amd64 is passing without error.

The errors seem to come from _netCDF4.pyx
Does it just need a rebuild?

e.g.

Later there are other errors, "OSError: [Errno 28] No space left on device"


scipy 1.12 should be uploaded to unstable in the near future,
which would make this bug serious.
