Overview
| Comment: | Fix a typo on the ynVar typedef that unfortunately caused 3.6.20 to be released with a "bug" that causes excess memory usage for Expr objects. This bug should be benign in the sense that the correct answer is still always obtained - it only uses more more memory than is really necessary. |
