Windows supported?

[jgranduel]

Hi,

I thought that frawk was not supported on Windows, but I came about this #87 issue where I saw that using cargo build --no-default-features does (or might) compile. I don't know anything about jemalloc, so it was just a test. I don't know if it was relevant to try!

It compiled indeed, with 3 warnings (cargo --version ⟶ cargo 1.73.0 (9c4383fb5 2023-08-26)).

warning: use of deprecated method `itertools::Itertools::fold_results`: Use .fold_ok() instead

    |          ^^^^^^^^^^^^

   |         ^^^^^

   = note: `#[warn(dead_code)]` on by default

warning: `frawk` (bin "frawk") generated 2 warnings
    Finished dev [unoptimized + debuginfo] target(s) in 47.86s

But, it hanged at first trial:

assertion failed: !map.is_null()
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

so with RUST_BACKTRACE=1

Thanks! Would be happy have frawk running on Windows as there is no up to date solution, AFAIK.

I believe this is the same as #101 , which indeed points to an issue on Windows when running frawk using the default settings.
