Sorry I misunderstood you. Never seen a graph crashing.

Your lpcsynthesis_tilde_perform() method is simple and you've probably
checked pointer arithmetic a dozen times. Yet valgrind attributes invalid
reads and writes to it. How frustrating. Pd does not crash, the invalid
access is probably happening within it's allocated space. Best thing would
be if you can force Pd to crash on it. Instantiate a lot of your objects,
delete some of them, or close/open patch several times etc. Pd's allocated
memory is not a continuous block. Under circumstances, Pd must crash on an
illegal access, and you'll be pointed to the culprit code. Well this is my
not-so-educated guess. I've had similar situations with my own homebrew
objects. Good luck anyway.
