(with WASM_OBJECT_FILES set by default) fails on the clang command,

fatal error: error in backend: section size does not fit in a uint32_t
clang-8: error: clang frontend command failed with exit code 70 (use -v to see

clang version 9.0.0 (<a href="mailto:git@github.com">git@github.com</a>:llvm-mirror/clang.git

Target: wasm32-unknown-unknown-wasm
===

Compiling natively with clang does not throw an error if the target is
/dev/null, and changing /dev/null to something else unbreaks the wasm target.</pre>
