Is this the right board to report this? Call it a “code review.”
Try this in the Nyquist prompt, no matter how small the selection, and watch memory usage of the Audacity process:
(dotimes (i 10000000)
(snd-maxsamp s))
Untried fix: at line 106 of samples.c, change
return (double) (s->scale * result);
to
{ double the_result = (s->scale * result); sound-unref(s); return the_result; }
(This on just my first day of digging into the sources. Time to install an actual compiler and debugger, I suppose.)
