GPL Ghostscript 9.50: Unrecoverable error, exit code 1

I would suspect ghostscript.

Things like that:

<<<<

The file access control capability (enable with -dSAFER) has been completely rewritten, with a ground-up rethink of the design. For more details, see: SAFER.

It is important to note that -dSAFER now only enables the file access controls, and no longer applies restrictions to standard Postscript functionality (specifically, restrictions on setpagedevice). If your application relies on these Postscript restrictions, see OLDSAFER, and please get in touch, as we do plan to remove those Postscript restrictions unless we have reason not to.

IMPORTANT: File access controls are now enabled by default. In order to run Ghostscript without these controls, see NOSAFER

I think something (gl2ps?) used to generate eps files with "setpagedevice"

 

These problems appear to be repeatable.  It doesn't affect all the
figures.  I don't recall seeing these before.  Is it just me, or is
anyone else seeing these problems?
