This is not a supported combination. You are likely to run into additional problems with this. Please use `lld` instead when using clang. The a.out file is created by the linker, not the compiler, so this likely happens either due to a bug in the binutils `ld`, or due to some combination of clang and ld. ------------- PR Comment: https://git.openjdk.org/jdk/pull/24125#issuecomment-2743244239
