You will find out that the build failed during F32 mass rebuild <https://koji.fedoraproject.org/koji/taskinfo?taskID=41318028> on ppc64le and aarch64. The ppc64le failure is: -- Performing Test CXX_mvsx_COMPILE_WORKS - Failed -- Flag was accepted, but it did not build test source (this could be due to either the compiler or binutils) -- Performing Test CXX_maltivec_mabi_altivec_FLAG_ACCEPTED -- Performing Test CXX_maltivec_mabi_altivec_FLAG_ACCEPTED - Success -- Performing Test CXX_maltivec_mabi_altivec_COMPILE_WORKS -- Performing Test CXX_maltivec_mabi_altivec_COMPILE_WORKS - Failed -- Flag was accepted, but it did not build test source (this could be due to either the compiler or binutils) -- Performing Test CXX_qarch_auto_qaltivec_FLAG_ACCEPTED -- Performing Test CXX_qarch_auto_qaltivec_FLAG_ACCEPTED - Failed -- Performing Test CXX_COMPILE_WORKS_WITHOUT_SPECIAL_FLAGS -- Performing Test CXX_COMPILE_WORKS_WITHOUT_SPECIAL_FLAGS - Failed -- Could not find any flag to build test source (this could be due to either the compiler or binutils) CMake Error at cmake/gmxManageSimd.cmake:51 (message): Cannot find IBM VSX compiler flag.

See also "/builddir/build/BUILD/gromacs-2019.5/serial/CMakeFiles/CMakeOutput.log". See also "/builddir/build/BUILD/gromacs-2019.5/serial/CMakeFiles/CMakeError.log". Koschei history <https://koschei.fedoraproject.org/package/gromacs> claims the build started to fail with these changes <https://koschei.fedoraproject.org/build/7747640>. It's probably a triggered by an upgrade of GCC to 10 version. SIGILL means the processor met an instruction it does not understand. In your case procps-ng package seems to be miscompiled (or run on an incopatible hardware). I recommend getting a shell in the mock enviroment (mock --shell) and investigeting whether the ps program works there). My gut feeling is that GCC 10 started to omit new instructions and your hardware is not compatible with them. Can you reproduce it on one of these machines <https://fedoraproject.org/wiki/Test_Machine_Resources_For_Package_Maintainers>? -- Petr
