// new rust version doesn't fail on this, so this is definitely a bug in c++ builds only
// - reproduced with remote: origin/Integration_3.7.1
// make
// set PATH /Users/wes/repos/github/fish-shell/fish-shell/build $PATH

// FYI traced back to this line: https://github.com/fish-shell/fish-shell/blob/tmp3.7.1/src/reader.cpp#L4763
//
// rust build works:
// gcob master
// cargo build
// set PATH /Users/wes/repos/github/fish-shell/fish-shell/target/debug/ $PATH
// node exec-file-sync.cjs # this script
// # works fine! perhaps I should start running the rust build :) and give feedback on bugs anyways?

// show buffer text:
