Segfault running wasm-pack build #68

Describe the Bug

I'm working through to Game of Life tutorial at https://rustwasm.github.io/docs/book/game-of-life/hello-world.html

Running wasm-pack build results in a segfault after the Compiling wasm-bindgen v0.2.84 status line. Shell prompt returns, but compiling completes in the background, muddying shell prompt. No files are added to the pkg/ directory.

Steps to Reproduce

  1. Clone template with cargo generate
  2. cd into generated directory.
  3. Run wasm-pack build

Expected Behavior

wasm-pack build should complete without error and produce files in pkg/ directory, as described in the tutorial link above.

Actual Behavior

Segfault, apparently during "compiling wasm-bindgen". No files are added to pkg/ directory.

Running wasm-pack build a second time shows the segfault after "Installing wasm-bindgen"

Additional Context

cargo 1.67.0 (8ecd4f20a 2023-01-10) on Archlinux, kernel 6.2.2-zen1-1-zen

A .wasm file is generated in target/wasm32-unknown-unknown/release/, but I'm guessing it is meant to be copied to pkg/ during the failed portion of the build.
