SIGSEGV when running a basic jester 0.6.0 server in nim 2.0 on M1 Mac

[sklarsa]

I have a simple file:

import htmlgen
import jester

routes:
  get "/":
    resp h1("Hello world")

and when I compile, I get the following output:

$ nim c -r --gc:orc src/server

I'm having the same issue:

import jester
import htmlgen

routes:
  get "/":
    resp h1("Guten Morgen")

Running it runs into a SIGSEGV:

Just found a work around:

You can add -d:useStdLib in your nim.cfg,
and jester will use std/asynchttpserver instead of httpbeast.

And it works!

@danny1113 - this should also be solved in PR #89 . httpbeast git-tag is not updated yet, so you need to either use #head or manually cloning and installing.
