Sounds like there's a memory leak. I'll bet your
code opens the font with GrCreateFont and
then draws, then destroys the font?
It might be interesting to try the following, to help debug:
1. GrCreateFont using a built-in font, and see whether you
still have a memory leak. If so, it's likely in your program.
2. Otherwise, we've likely got a leak in the pcf reader,
and the destroyfont function probably doesn't release
all the memory. A quick review of engine/fonts_pcf.c
should determine this.
