The Inkscape v1.1 build fails on amd64, because of a regression test called "text-gzipped-svg-glyph", which can be found here:
https://sources.debian.org/src/inkscape/1.1-1/testfiles/rendering_tests/text-gzipped-svg-glyph.svg/ from the build log: Start 301: render_text-glyphs-vertical 301/303 Test #301: render_text-glyphs-vertical ........ Passed 2.25 sec Start 302: render_test-powerstroke-join 302/303 Test #302: render_test-powerstroke-join ....... Passed 0.55 sec Start 303: render_text-gzipped-svg-glyph 303/303 Test #303: render_text-gzipped-svg-glyph ......***Failed 0.26 sec text-gzipped-svg-glyph FAILED text-gzipped-svg-glyph-large SKIPPED 99% tests passed, 1 tests failed out of 303 On i386, the build succeeds, apparently because this test does not run at all: Start 301: render_text-glyphs-vertical 301/302 Test #301: render_text-glyphs-vertical ........ Passed 2.65 sec Start 302: render_test-powerstroke-join 302/302 Test #302: render_test-powerstroke-join ....... Passed 0.94 sec 100% tests passed, 0 tests failed out of 302 If this test is not required on i386 (and presumably other architectures where the build succeeds), then it shouldn't be required on amd64, either. This discrepancy needs to be investigated.
