In gcc-15, explicit includes of <cstdint> are required when fixed-size integers are used. In this file, this include only happened as a side effect of including SmallVector.h

Although llvm compiles fine, the root-project would benefit from explicitly including it here, so we can backport the patch.

Maybe interesting for @<!-- -->hahnjo and @<!-- -->vgvassilev
