It seems you have so many (157) seams that some of them are quite
short (only two entries). Apparently two entries is not a problem,
except for the situation where they are the wrong way around: The
first should not be moveable(*). So having corrected the code for
making sure that the first one is (non)movable, enblend runs just
fine.
The patch for enblend is attached.
George's village hotel now stitches just fine at 12000x6000.
Roger.
(*) Or the other way around, I don't care. Too many negatives makes my
head spin.
