Indeed, there are rendering issues in the raw CFF font `cmex10'
embedded in the PDF: I get many `stack underflow' tracing messages
using the old CFF engine. However, if you use the new CFF engine, all
glyphs are displayed correctly.
Note that the `stack underflow' messages are correct actually since
the constructed `cmex10' font is buggy: For example, glyph 5 contains
`vhcurveto' with zero arguments as the very last operator which is
invalid according to the Type 2 specification. In other words,
FreeType's old CFF engine is correct, and you should fix your
application's CFF builder.
