When compiling sandbox-2.35 on ARM64 using Clang as system compiler. Using LTO or noLTO does not change, the issue is a pointer conversion in /libsandbox/trace/linux/aarch64.c in the do_ptrace function, resulting in the error incompatible integer to pointer conversion passing 'int' to parameter of type 'void *' [-Wint-conversion] Reproducible: Always Steps to Reproduce: 1. Set clang as system compiler on ARM64 2. Compile Sandbox-2.35 3. Emerge breaks Actual Results: incompatible integer to pointer conversion passing 'int' to parameter of type 'void *' [-Wint-conversion] Expected Results: Clean compilation

I don't think that should be an error under normal circumstances. Do you have any relevant settings (like Werror=int-conversion) in /etc/clang?
Created attachment 865340 [details, diff] libsandbox/trace: cast NT_ARM_SYSTEM_CALL to void * Please test this patch. You should be able to place it at /etc/portage/sys-apps/sandbox/.
Comment on attachment 865340 [details, diff] libsandbox/trace: cast NT_ARM_SYSTEM_CALL to void * Never mind, I also need to cast to an appropriate integer size.
