self-cycle not reported through the tool

[bsansouci]

When a module references itself, nothing shows up until you get a notification in vscode that the server has crashed.
Looking at my terminal, I saw the error message FAILED: MyAwesomeModule has a self cycle

That's intriguing. Example?

To be re-opened with an example.

Example! Add a file A.res in your codebase, in it put:

let a = 10

Js.log(a)

Everything typechecks and builds, now change it to

let a = 10

Js.log(A.a)

The server crashes and you get a popup that says "Wanna start the server", you do it 5 times and then it says it crashed 5 times. It never reports that the error is that there's a cycle, but that error gets reported if you manually run bsb.

Same as this:
#220

Though there's the comment about crashing, too.

I suspect it fails when parsing this:

#Start(1620252447923)
FAILED: A has a self cycle
#Done(1620252448018)

Can repro the crashing too.

Just revisited this. For context: self-cycle error goes to compiler.log, but cycle of size 2 or more the log is empty. Cannot be solved in the editor without a compiler fix.
