3070 :: No stacktrace when compiling with -d:useNimRtl

• Serenitor (orginal) [2017-07-26T23:53:48+02:00] view original

  As the subject line states, when compiling with useNimRtl, I no longer get any stacktrace information (regardless of stackTrace:on, lineTrace:on, etc.), which looks - for example - like this:

  
  No stack traceback available
  SIGSEGV: Illegal storage access. (Attempt to read from nil?)
  Run

  Here's a little test case:

  main.nim, compile with nim -d:useNimRtl c main:

  type sequence = seq[int]
  
  proc test =
      var s: sequence
      s[0] = 1
  
  test()
  Run

  Here's how to compile your nimrtl: https://nim-lang.org/docs/nimc.html#dll-generation

  Here's the output I expect to get (and that I do get when omitting -d:useNimRtl):

  
  Traceback (most recent call last)
  main.nim(8)              main
  main.nim                 test
  SIGSEGV: Illegal storage access. (Attempt to read from nil?)
  Run

  Someone please tell me that there's a way to resolve this. Debugging without stacktraces is not... particularly fun. :(
