I can reproduce it easily with gcc-10 and gcc-11 but not with gcc-9. The powerpc 7400 support has been broken since the beginning of gcc-10 development. After the commit [1] removing -many from the options passed by default to the assembler, the build of this defconfig fail with assembler errors: arch/powerpc/perf/bhrb.S: Assembler messages: arch/powerpc/perf/bhrb.S:22: Error: unrecognized opcode: `cmpldi' arch/powerpc/perf/bhrb.S:24: Error: unrecognized opcode: `ld' arch/powerpc/perf/bhrb.S:25: Error: unrecognized opcode: `sldi' It was fixed later by the commit [2] before the gcc-10 release but glibc segfault at runtime since then. The Buildroot gitlab-ci testing only test with uClibc-ng libc but I try sometime with Glibc... but I missed this issue. This issue should be reported to gcc.
