pdftocairo generates PS that crashes Adobe engine
When some PDFs are converted to PS by pdftocairo using cairo 1.15.10 or later, the resulting PS files crash printers that are using Adobe PS engine. In my case, Ricoh printers.
Adobe reviewed the PS files and said this:
Cairo incorporates pattern data into form data. When printing, the form data is drawn repeatedly, but the cache memory overflows because the pattern data is included. Due to this, an illegal memory access occurs and the job is canceled.
If Cairo does not include pattern data in the form data, it is possible to work around the problem.
Does this pattern data need to be included in the form? Perhaps it's still possible to return to 1.15.8 behavior, or pinpoint the commit that I could remove just for my environment?
Here are two example PDF files, and two resulting PS files for each PDF.
Cairo 1.16.0 (I'm using 1.16.0 in this example, but the issue occurs with 1.15.10 onward).
