Description bernhard.jungk 2014-07-30 08:51:08 UTC
When using the mono assembly in .NET, CompilerError.ToString() crashes because it contains the following statement:

if (FileName.Length > 0) {

The CompilerErrors were created with:

TextTransform.cs:58 Errors.Add (new CompilerError (null, -1, -1, null, message));

and

TextTransform.cs:63 var err = new CompilerError (null, -1, -1, null, message) {
TextTransform.cs:64   IsWarning = true,
TextTransform.cs:65 };

Could you please provide us the test steps you followed. If possible, attach a small complete project that demonstrates this behavior.

Also can you please add the logs from the following places?:
