Hello once again,

after fixing the alignment problem, my compilation now fails a couple of pages later: luatex crashes with SIGFPE when trying to write a PK font.

I do not have a simple test case yet, but I think I see the problem in the source: in source/texk/web2c/luatexdir/font/writet3.w, function writepk(), one call to pdf_printf() divides by newdpi, which can be zero when pk_fixed_dpi is not set.

What is the intention behind dpi vs. newdpi?

I remember something ... I will give it a look.

but of course a mwe is still much appreciate :-)
