When I try to use cargo expand I get this output:

$ cargo +nightly expand
    Checking crate-name v0.1.0 (/path/to/crate)
    Finished dev [unoptimized + debuginfo] target(s) in 0.23s

memory allocation of 7881122326526296064 bytes failed
fish: Job 1, 'cargo +nightly expand' terminated by signal SIGABRT (Abort)

I'm not sure I can give much more information.

Can you share:

  • Version of nightly (try the latest if possible)
  • Version of cargo-expand
  • Which platform (x86_64-unknown-linux-gnu? x86_64-apple-darwin?)

If you'd be willing to debug it, I might suggest using gdb or lldb to see where the allocation is being made.

This is a regression in the syntect crate — trishume/syntect#412. It should work again if you reinstall with cargo install cargo-expand --force because a workaround was published a couple days ago.
