<p style="text-align: left; background-color: rgb(255, 255, 255); margin: 0px;"><span style="font-family: Aptos, sans-serif; font-size: 12pt; color: black;">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 </span><span style="font-family: Arial, sans-serif; font-size: 11.5pt; color: rgb(29, 28, 29); background-color: rgb(248, 248, 248);">(libpixman-1-0:s390x) package from version 0.40.0-1 to
version 0.42.2-1, the test suites failed</span><span style="font-family: Aptos, sans-serif; font-size: 12pt; color: black;"> in the librsvg.</span></p>

<p style="text-align: left; background-color: rgb(255, 255, 255); margin: 0px;"><span style="font-family: Aptos, sans-serif; font-size: 12pt; color: black;">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 </span><span style="font-family: Arial, sans-serif; font-size: 11.5pt; color: rgb(29, 28, 29); background-color: rgb(248, 248, 248);">0.40.0-1

<p style="text-align: left; background-color: rgb(255, 255, 255); margin: 0px;"><span style="font-family: Aptos, sans-serif; font-size: 12pt; color: black;">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...!</span></p>
