+title: Test fixture exercising parser corner cases
+
+description: |
+ Covers patterns that previously broke the classifier:
+ - "/* ... */ code;" with code following the closing of a one-line
+ block comment must still parse the code.
+ - a label on a node whose name starts with a digit (1wire@10).
+ - a multi-line C preprocessor macro using backslash continuations
+ must not be parsed as DTS lines.
+ - a /* comment that opens and closes on the same code line must
+ not leave the parser in block-comment state.
