You are using wasmtime 0.37. The latest released version is 0.40.1. Can you check if it is fixed with 0.40.1?

look like the compilation unit is too big.
Wasmtime GitHub notifications bot (Sep 06 2022 at 13:58):alexcrichton commented on issue #4865:
This is a slightly minimized input, but I believe that @yuyang-ok is right in that this input is seemingly too large for regalloc2. Presuming that this isn't easy to fix within
regalloc2(cc @cfallin) we will want a better error for this, so one thing we could try to do is limit the number of instructions per function. I'm not sure if browsers do that already to draw inspiration from.
Wasmtime GitHub notifications bot (Sep 06 2022 at 15:23):cfallin commented on issue #4865:
It almost certainly is a too-large function indeed; there is a limit of 2M vregs due to performance-critical bitpacking tricks. Will take a closer look tomorrow when I’m back at a computer!
