vapoursynth memory usage goes mad if range>30

[Statick]

if I set range=28 (or any lower value) the memory usage of my encoding application Staxrip with the script loaded (with loads of other plugins involved) is stable at about 50-100mb
if I set range=32 the memory usage increases to around 4gb before python crashes with an out of memory error
using sample_mode=5 if that makes any difference

# works fine
clip = core.neo_f3kdb.Deband(clip, sample_mode=5, range=28, y=256, cb=256, cr=256, keep_tv_range=True, grainy=0, grainc=0)

# destroys RAM
clip = core.neo_f3kdb.Deband(clip, sample_mode=5, range=32, y=256, cb=256, cr=256, keep_tv_range=True, grainy=0, grainc=0)

CHECK_PARAM(ep.range, 0, 31);

Range is supposed to be within 0-31. Do you not see any error message?

[Statick]

well that makes sense then lol

no, there's no error messages from putting the value 32, it's happy for me to do that and for the encode to begin, and then it crashes with an out of memory error. there's no documentation that says max 31 either, so no way of knowing that this was an invalid value, so at least I know now this is a max value and I'll keep it lower than that in future

@Statick, is this still issue? I cannot reproduce it with range=32 with the latest version.
