Wrong stack trace when exception is raised in template

[simonkrauter]

Description

I found a case, where getStackTrace() returns the line number of the raise statement inside the template definition, instead of the line number of the template instantiation.

Test program:

type Severity = enum
  fatal
  regular

template raiseError*(severity: Severity) =
  if severity == fatal:
    raise newException(Defect, "error")

proc main() =
  try:
    raiseError(fatal)
  except:
    echo getCurrentException().getStackTrace()

main()

Note: Without the ìf statement it works correct.
