The problems are caused by clisp's usage of -fwrapv, where the
developers implicitly assume this also makes pointer wrapping defined.
After https://github.com/llvm/llvm-project/commit/1295aa2e814 however,
-fwrapv no longer implies that, and you either have to add a clang
specific -fwrapv-pointer option, or use -fno-strict-overflow, which
works for both clang and gcc.
