[Debian-astro-maintainers] Bug#838424: casacore: FTBFS on arm64 and s390x: several tests fail

[Aaron M. Ucko]

Source: casacore
Version: 2.1.0-2
Severity: important
Justification: fails to build from source

Builds of casacore on arm64 and s390x still encounter several test
failures even with -fsigned-char in effect:

- Tests 244 (tLSQaips), 245 (tLSQFit), 353 (tLCEllipsoid), and 431
  (tFITSExtImage) fail with identical numeric discrepancies.

- Tests 274 (tClassicalStatistics) and 282 (tHingesFencesStatistics)
  both fail with no further details reported.

Could you please take a look?

Thanks!
