Hello Richard, The test results are impacted by Execution procedure OR by Changes in glibc. Execution procedure: I tested the glibc with the cross-compiler method given in https://sourceware.org/glibc/wiki/Testing/Testsuite for the aarch64 architecture on qemu. However, based on our past test experience, we're following a few additional steps like copying the 'glibc-locale/2.28-r0/image/usr/*' to booted qemu image /usr/ directory (This step is not mentioned the glibc wiki) etc. Also, the glibc test is aborted when the -Werror=format-security flag is used and to get the test done we've removed this error flag and compiled glibc sources. Since the glibc test not performed very frequently, I am not sure the additional steps what we followed are obsolete or not. I am now working on adhering to the test procedure mentioned in the glibc test wiki and will see the results. Changes in glibc: To comment on the code change impact on the test failures I've to look into each failed test case by case and what are the changes in glibc and how it is impacting the test. I'll keep you posted on this and since the glibc test execution is taking a lot of time my response may be delayed. Thanks, Sundeep K. > > Cheers, > > Richard > > >
