deno fmt lexical parse error

[aricart]

If you have some dodgy code like this:

export class X {

  constructor() {
  }
  bad(target :number) {
    const d = 1;
    const min = 0;
    const max = 100;
    console.log("x", `duration ${d} not in range - ${min} ≥ ${d} && ${max} ≥ ${d}`),;
  }
}

Note the trailing , before the ;.

and run deno fmt, you get:

❯ deno fmt
memory allocation of 18446744073709551615 bytes failed
[1]    8481 abort      deno fmt

I tried this and I found that the parser reports errors for this.

@kdy1 yeah, this is a dprint problem with its code for printing diagnostics. See here: dprint/dprint-plugin-typescript#113 (comment)
