Dear Maintainers, This issue also causes jpeg-xl to fail build from source[1]. The root cause is missing test file:
Note: Google Test filter = SplinesTest.Drawing [==========] Running 1 test from 1 test suite. [----------] Global test environment set-up. [----------] 1 test from SplinesTest [ RUN ] SplinesTest.Drawing ReadTestData /usr/share/libjxl-testdata/jxl/splines.pfm Program received signal SIGILL, Illegal instruction. jxl::test::ReadTestData (filename=...) at /usr/src/jpeg-xl-0.11.1-6ubuntu2/lib/jxl/test_utils.cc:90 warning: 90 /usr/src/jpeg-xl-0.11.1-6ubuntu2/lib/jxl/test_utils.cc: No such file or directory (gdb) where #0 jxl::test::ReadTestData (filename=...) at /usr/src/jpeg-xl-0.11.1-6ubuntu2/lib/jxl/test_utils.cc:90 #1 0x000055555557e1f1 in jxl::SplinesTest_Drawing_Test::TestBody (this=<optimized out>) at /usr/src/jpeg-xl-0.11.1-6ubuntu2/lib/jxl/splines_test.cc:293 #2 0x00005555557093d7 in void testing::internal::HandleExceptionsInMethodIfSupported<testing::Test, void>(testing::Test*, void (testing::Test::*)(), char const*) () #3 0x00005555556eecae in testing::Test::Run() () #4 0x00005555556eee35 in testing::TestInfo::Run() () #5 0x00005555556f9c47 in testing::TestSuite::Run() () #6 0x00005555556fedbc in testing::internal::UnitTestImpl::RunAllTests() () #7 0x0000555555709a37 in bool testing::internal::HandleExceptionsInMethodIfSupported<testing::internal::UnitTestImpl, bool>(testing::internal::UnitTestImpl*, bool (testing::internal::UnitTestImpl::*)(), char const*) () #8 0x00005555556eeeca in testing::UnitTest::Run() () #9 0x0000555555573b76 in main () (gdb) quit cat /usr/share/libjxl-testdata/jxl/splines.pfm cat: /usr/share/libjxl-testdata/jxl/splines.pfm: No such file or directory (os error 2) which is expected behaviour due to upstream testsuite crashing when the test file is not found.
