7434 :: Cryptic error message without specific hints

• drkameleon (orginal) [2021-01-26T10:11:17+01:00] view original

  I've been doing some code refactoring and I ended up having this error:

  
  .fatal.nim(49)            sysFatal
  Error: unhandled exception: 'ident' is not accessible using discriminant 'kind' of type 'TNode' [FieldDefect]
  Run

  And that's all I get.

  Any pointers as to where I look? (I obviously have several (ref) objects, with case ... of ... fields, so it must be one of them, but I have no idea what this actually might mean...)

  I've just spotted this:

  https://github.com/nim-lang/Nim/issues/15707

  So... has it been fixed? On devel?

  Just tried with:

  
  Nim Compiler Version 1.5.1 [MacOSX: amd64]
  Compiled at 2021-01-26
  Copyright (c) 2006-2021 by Andreas Rumpf
  Run

  Still nothing.

  Any ideas?

  TNode is the internal node data structure of the compiler, this is a compiler error. If you clone the Nim repo and build a debug compiler you will get a more descriptive error message. Do you have a reproducible example?

  I'm still struggling to figure out what is going on. The codebase is rather big, so it's very difficult to isolate the bug. I've experimented with commenting in/out different parts of the code and I tend to believe that the error has to do with nested templates.

  When/If I have something more concrete, I will open an issue.
