coremark-minimal.wasmはwasm3公式のCoremarkのwebassembly移植版で，coremark-minimal版はcoremark本体にwasmで使えるための改変が施されている(coremark.wasm,coremark-emcc.wasmはそのままビルド)
READMEより
minimal build is more complex, and requires modification of core_main.c.
coremark-minimal.wasmを逆アセンブルして見ると，線形メモリの消費は1ページのみであり，対象とするすべてのマイコンでmemory allocation failedにならず測定できる可能性が高い
