hmm. i am sure i have asked a lot of times which gfx-card you use (and i am sure
you have answered this quite often).
anyhow *if* you are using an nvidia card try to install their openGL-headers
(ships with the nvidia-glx-package) instead of the mesa-headers

so still the same:
what is puzzling me, is why pd tries to destroy the text3d object.
why is the pd_free() called ?
who is trying to call pd_free() ?
could you compile pd with debugging-flags (or rather: without non-debugging and
optimization flags) and tell us, what gdb thinks about the ?? functions ?
