I was affected by bug 487 using microtype's protrusion=true. Digging around, I found that the error lies in round_xn_over_d (pdfgen.w). Please find attached a patch to correct the issue.

Applied, thank you.

Aside: I wonder whether its method to calculate still makes sense, given modern compiler optimizations. What about something along the lines of..? unsinged long long t = x * n; t = t % d; if (t > INT_MAX) arith_error = true; return (scaled) t;

Yes, the current version looks weird, but I want to keep it as-is until I have time to do a more global cleanup. Best wishes, Taco
