Which kind of error? An error message by the compiler? One by the 
linker? The compiler crashes?

If you don't tell us what happens exactly, and a simple example 
code that triggers the issue, we don't know what to do.

If your codebase is big and you don't manage to reduce it to a 
couple lines to show the error, you can try dustmite [1].
