[Version 4.4] Prepare font stack overflow

[Claus Eggers Sørensen]

I just installed VTT 4.4, opened a font and went Tools > Prepare font… and got this:

Code:

Pre-Program
Critical Error: Inst: MPPEM Stack Overflow.
At ByteOffset: 3 Of function: 83

Attached the TTF.

The maxp table is problematic in this font--have any tools changed this table?
Specifically the maxStackElements is causing the immediate problem you report, but the maxFunctionDefs and maxStorage are also problematic.

Hi Greg
The TTF is generated from Fontlab build 4283. Will you open a bug-report on this?
