Description Jonathan Chambers 2016-10-12 16:44:59 UTC
Use of `#pragma` causes incorrect line numbers. Note the line number changes when a pragma is (un)commented.

With pragma commented:
System.Exception: Exception of type 'System.Exception' was thrown.
  at MainClass.Main (System.String[] args) [0x00002] in /Users/jonathan/Development/Bugs/CompilerPragmaLineNumber/Program.cs:11 

With pragma uncommented
System.Exception: Exception of type 'System.Exception' was thrown.
  at MainClass.Main (System.String[] args) [0x00002] in /Users/jonathan/Development/Bugs/CompilerPragmaLineNumber/Program.cs:12

// Test case
using System;

// #pragma warning disable 0169

class MainClass
	public static void Main(string[] args)
			throw new Exception();
		catch (Exception ex)

I cannot reproduce this with master or Mono 4.8. I fixed similar issue recently so you are probably just commits behind.
