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
   --> src\runtime\writers.rs:688:10

688 |         .fold_results(true, |a, _| a)
    |          ^^^^^^^^^^^^
    |
    = note: `#[warn(deprecated)]` on by default

   |         ^^^^^

   = 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:

thread 'main' panicked at src\codegen\intrinsics.rs:1398:1:
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.

Sorry, just realising I had posted here something relevant to the frawk project. I apologize for this error.
