Fl.lookup: Crash in clip mode with no table input

[Owen Green]

What?

fl.lookup~ will crash when in /mode clip when nothing is attached to the middle inlet.

0   AHarker.fl-lookup-              0x000000011ce30931 void table_read<cubic_hermite_reader, FrameLib_Lookup::FetchClip, double, double>(FrameLib_Lookup::FetchClip, double*, double const*, long, double) + 369
1   AHarker.fl-lookup-              0x000000011ce2e85a void table_read<double, double, FrameLib_Lookup::FetchClip>(FrameLib_Lookup::FetchClip, double*, double const*, long, double, InterpType) + 442

I haven't tried other interpolation modes.

Expected

That it doesn't crash, as in /mode zero

Workaround

/mode zero then fl.split?
