I'm still getting compilation errors when compiling in debug mode with the latest nightly:

   ...
   Compiling parking_lot v0.5.5
LLVM ERROR: out of memory
error: Could not compile `num-rational`.

This happens consistently on multiple PCs. Release Builds work just fine.

To reproduce build the livesplit-core crate with cargo build -p cdylib --target wasm32-unknown-unknown

This looks like an LLVM issue, which is a bit more clear to identify if LLVM with assertions enabled is used --

UNREACHABLE executed at /checkout/src/llvm/lib/Target/WebAssembly/WebAssemblyCFGStackify.cpp:252!

I'll work on minimizing this and submitting a bug to upstream LLVM

This may have been fixed by https://bugs.llvm.org/show_bug.cgi?id=36564 which we haven't cherry-picked yet, testing now

Ok confirmed to be fix by that, I'll go do the backport now.
