Fix bidi-line-level-loop boundaries |
|
|
|
The first change was caught using dynamic code analysis and prevents |
|
access to uninitialized memory (it wouldn't be worse than that, though, |
|
given we do not access memory we are not allowed to and the consequences |
|
are harmless). |
|
|
|
The second change was found by eyesight. |
