No, it does not work for me with your `panicoverride.nim`.

The problem **is** associated with " **==** ".
@leorize, by changing "standalone" to "any", the error is gone. **But** , in
this case, some warnings appear (Warning: '....' uses GC'ed memory), and
`panicoverride.nim` is not needed any more. See `fatal.nim`:
when hostOS == "standalone":
include "$projectpath/panicoverride"
proc sysFatal(exceptn: typedesc, message: string) {.inline.} =
panic(message)
....
Run
So, `--os:any` is not a replacement of `--os:standalone`.
