Subject: [PATCH] Fix crash on exit introduced in previous commit
|
|
|
4558d1 |
|
|
|
4558d1 |
When the number of layers is greater than 2, as in Chomsky.sfd and most
|
|
|
4558d1 |
of my other fonts, FontForge will crash on exiting.
|
|
|
4558d1 |
|
|
|
4558d1 |
This is just a simple mistake @skef made.
