Description:
Building LLVM (with mlir, clang, and flang) using GCC 14.3.0 fails in the following environments:
Environment:
macOS AArch64 with GCC 14.3.0 (with and without Nix sandbox)
aarch64-linux with GCC 14.3.0 (via Nix sandbox on server)
Expected Behavior:
LLVM and its subprojects (flang, mlir) should build successfully with GCC 14.3.0.
Notes:
The issue appears to stem from incompatibilities between libc++ and libstdc++ during the build process.
See discussion from [nix pr](https://github.com/NixOS/nixpkgs/pull/428306)
