Bug#1038447: librsvg: FTBFS on big-endian architectures: multiple test regressions since September 2022

[Gayathri Berli]

Hi Debian folks,



After a lot of debugging, by upgrading librsvg and its dependency packages one after another like libcairo, libpixman and libpango, we found out that while upgrading libpixman (libpixman-1-0:s390x) package from version 0.40.0-1 to version 0.42.2-1, the test suites failed in the librsvg.



I built these packages ( i.e. cairo, pixman & pango) manually from their respective sources by resolving all the version dependencies and ran the librsvg tests to make sure that the test suites failed while upgrading pixman package from 0.40.0-1 to version 0.42.2-1..



By doing git-bisect on pixman package commits, I figured out the below mentioned commit which has changes w.r.t. big-endian architectures, introduced the regression.. But I checked the main line repo of pixman and I see that the test suites are passing. I will check further on this and post my updates...!
