gdb trace log: THROW_PATENDED is reached.

I set breakpoint on src/ttinterp.c:223 (defines THROW_PATENDED)
and execute the sample PS file. As I attached log, the execution
is interrupted - gs reached to THROW_PATENDED (it seems that
THROW_PATENDED executed only once). However, I cannot check
the rasterization result if THROW_PATENDED is skipped, because
Apple hinting patent might be registered.
