            Bug ID: 42487
           Summary: Free Devanagari font Samanata crashes during GPOS
                    processing
           Product: Wine
           Version: 2.2
          Hardware: x86
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: usp10

test file

Opening attached file in notepad with Samanata font of size >=10 crashes on
invalid memory access in uniscribe.

Font is available with debian package fonts-deva-extra (3.0-3):

c21d338d8a6efa48a67b9cc0cde6b0b493bafc6f  samanata.ttf

Font itself is broken, device table delta format is invalid in at least one of
the records, and ttx throws an exception when parsing GPOS too. However native
usp10 works fine.
