fx_stylize error on some styles

Software G'MIC

I’m getting an error using fx_stylize, but only when using certain style images.
I’m not sure what is wrong w/ the style image, but maybe because it’s black and white?

gmic i input.jpg i style.jpg +fx_stylize 1,6,0,0,0.5,2,3,0.5,0.1,3,3,0,0.7,1,0,1,0,5,5,7,1,30,5,2,1.85,0 o out.jpg

[gmic]./ Input file ‘style.jpg’ at position 1 (1 image 1000x644x1x1).

then it just hangs…

Another error I get is

[gmic] *** Error in ./fx_stylize/*repeat/*local/(…)/*local/*repeat/*if/stylize_match/ *** Command ‘move’: Invalid position 3 (not in range -2…1).

But in that case, it exits immediately
