Compiler insanity

[mjfh]

The following code

import config, core/chain # fails
#import core/chain, config # works

produces something like

nim-compile exited abnormally with code 1 at Tue Jul 18 12:29:14

whereas the code

#import config, core/chain # fails
import core/chain, config # works

compiles fine.

This goes along with other errors, maybe related to result.tryGet() (I am working n that.) A dirty fix for this particular one would be changing the line nim-chronos/chronos/apps/http/httptable.nim:80

let res = Base10.decode(uint64, ht.getString(key))

to

var res = Base10.decode(uint64, ht.getString(key))

I can't reproduce this -- what are the specific conditions under which it occurs?

[tersec]

Is this still reproducible now that nimbus-eth1 uses Nim 2.0.6?

[jangko]

Both chain and config have been refactored many times since this issue opened, I don't think this issue still reproducible because we don't know what exactly the problem is.
