Not much to add other than that these two fonts seems seriously broken in the hinting department. Before it even starts to loop, there is a stack overflow with the fpgm, then a lot of stack and storage abuse, before FreeType gave up on them doing too many backwards jumps. The backward jump loop is in the cvt/prep, which one can see from the FontVal report - the stack /storage abuse are cycling over the same byte offsets.

So the hinting in those two fonts are indeed rather broken. I'd like to have a look at the actual brokenness myself some times. FontVal 2.0 had a 2.6.x backend, and should show a generic 'value too high' error message for those two fonts - I hooked up all of FreeType's internal diagnosis one way or another, and when there is no existing specific error code from the old FontVal code base, one of the generic ones. The next substantial FontVal update already uses a more specific message for that specific brokenness problem. _______________________________________________ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
