on my side, I compiled flang with clang-18.1.8, configured with the following flags:
  -DLLVM_TARGETS_TO_BUILD=AArch64
  -DLLVM_INSTALL_UTILS=ON
  -DCMAKE_CXX_STANDARD=17
  -DLLVM_ENABLE_WERROR=OFF
  -DFLANG_ENABLE_WERROR=ON
  -DBUILD_SHARED_LIBS=ON
  -DLLVM_ENABLE_ASSERTIONS=ON
  -DLLVM_ENABLE_LIBCXX=On
  -DCMAKE_BUILD_TYPE=Release
  '-DLLVM_ENABLE_PROJECTS=llvm;clang;mlir;flang'
  -DLLVM_ENABLE_RUNTIMES=flang-rt
  '-DLLVM_LIT_ARGS=-v -vv'
and I confirm that it failed with flang from stage1
