I have one font which causes G4 to crash when exporting OTF.
Exporting the same file with G3 works fine.
When disabling both Remove Overlaps and Autohint it works fine.
When exporting TTF with Remove Overlaps and Autohint enabled it also works fine.
I have the same problem too, again.
G4: TT works, CFF crashes the app. Also when “Remove overlaps” and “Autohint” are disabled.
G3: Exports the same file in all formats without issues.
Version 4.2 (4200).
