Following Adobe implementation, copy only a few top elements of the stack
to the corresponding element of the $error dictionary when the stack
overflows. Adobe copies up to 500 top elements, we copy up to 65535. This
feature enables Ghostscript to have maximum stack sizes larger than 65535.
The maximum operand stack size is set to 100000 to match Adobe interpreters.
The large stack size is needed for some PDF files that construct large
dictionaries using << ... >> operators.
