+Subject: [PATCH] test: Disable optimization with clang for aligned_alloc.c
+
+Clang crashes when using glibc 2.35, it works ok with older glibc or
+musl, so its very specific problem. Its reported here
+
+https://github.com/llvm/llvm-project/issues/52765
+
+Until it is fixed, workaround the build failure
