New issue 131 by siguc... at gmail.com: Bug in Freetype plugin primitive
http://code.google.com/p/cog/issues/detail?id=131
primitiveLoadOutlineSizesFrom: aFace
uses non-existing ivar for reading flags:
interpreterProxy
storeInteger: FT2OutlineFlagsIndex
ofObject: rcvr
withValue: (self cCode: 'gs->outline.flags' inSmalltalk: [gs]).
(FT2OutlineFlagsIndex is nil) , causing overriding number of contours
(null=0=FT2OutlineContoursSizeIndex)..
which later causing VM crash when invoking primitiveLoadOutlineArraysFrom:
because of attempt to read outside of array range.
The fix is to remove the above code. (i wanted to attach file here, but
quota exceeded)
