To confirm that this remains an issue, I can reproduce it on utop v.2.6.0: ```ocaml $ utop ───────────────────────────────┬─────────────────────────────────────────────────────────────┬─────────────────────────────── │ Welcome to utop version 2.6.0 (using OCaml version 4.09.0)! │ └─────────────────────────────────────────────────────────────┘...

So I tried with a backtrace: ```ocaml $ env OCAMLRUNPARAM=b utop ───────────────────────────────┬─────────────────────────────────────────────────────────────┬─────────────────────────────── │ Welcome to utop version 2.6.0 (using OCaml version 4.09.0)! │ └─────────────────────────────────────────────────────────────┘ (* ... *) utop # "\158\214\149";;...

I understand that `utop` is maintained by the community. However I would appreciate if someone more familiar with the internals could briefly (a) confirm that I'm on the right track...

OK, I've now taken a look at this. I've managed to print the (invalid uft-8) string which ends up as question marks in the terminal. However I have not been...

I don't think it is unreasonable to expect that 80-90% of code hitting 5.00 upon release will be sequential (for a start at least). This indicates that the single-threaded-to-multicore transition...

- An option going in a different direction is to query the number of CPU cores at start-up via a bit of platform-dependent logic (`nproc`, `sysctl`, ...) and `mmap` accordingly....

@kayceesrk suggested we track a list of things broken by the additional memory requirements: For AFL-users any invocation of `afl-fuzz` without a `-m none` option or a large enough `-m`...

Ah, I forgot: Additional `char`/`string` generators ------------------------------------------------ Looking at another port (Hedgehog for F# I think) I spotted these signatures: ```ocaml val ascii : char t val latin1 : char...

Here's an alternative version of `Gen.bytes_size`: ```ocaml let bytes_size ?(gen = char) (size : int t) : bytes t = fun st -> let open Tree in let size_tree =...
