Bug#882421: segyio: FTBFS on sparc64: test_rotation: AssertionError: 1.571 != 0.0 within 3 places

[Aaron M. Ucko]

Source: segyio
Version: 1.3.3-1
Severity: important
Tags: upstream
Justification: fails to build from source
User: debian-sparc at lists.debian.org
Usertags: sparc64

The build of segyio for sparc64 (admittedly not a release
architecture) failed per the below excerpts from
https://buildd.debian.org/status/fetch.php?pkg=segyio&arch=sparc64&ver=1.3.3-1&stamp=1511256932&raw=0.
1.571 is of course approximately π/2.

Could you please take a look?

Thanks!
