File in question
I have a PDF (example attached) where parts of characters are missing. This is with cairo master, cairo 1.12.2 performs much worst on the same PDF.
So, with master:
* characters get clipped (look at the integral sign and the brackets)
And with 1.12.2:
* loads of characters are missing, but none of the visible ones are clipped

Rendered using cairo 1.12.2 (debian)
As I did not mention this yet. Rendered using:
pdftocairo -pdf error.pdf out.pdf
Can't reproduce this here with debian testing + cairo master (With cairo from debian testing, I do see the missing glyphs bug).
Any ideas on what might be different?
Sorry for the noise. Looks like the PDF produced by cairo master is correct, but is rendered wrong using older versions of cairo and poppler.
Rendering the pdf to png with pdftocairo (poppler and cairo master) or viewing it with "gv" everything is fine.
