Thank you. But should the interpreter crash though?
This program does not crash:
import("stdfaust.lib");
process = 1000 / hslider("divPitch", 10, 0, 10, 0.01);
While this one does crash:
import("stdfaust.lib");
process = os.osc(1000 / hslider("divPitch", 10, 0, 10, 0.01));
Thread 14 "Runner" received signal SIGSEGV, Segmentation fault.
