Original description

What steps will reproduce the problem?
1.Create a sketch with one tab and an error.
2.Compile.

What is the expected output? What do you see instead?

The error message says, for example, "Graph.cpp: In function '...'" instead of "Graph:In function '...'. If the sketch has multiple tabs, this is probably unavoidable (when we don't have a line number) because we don't know which tab is referred to.

Please use labels and text to provide additional information.
