Attached is the v7 patch. It includes the fix mentioned above. Also
this time the pattern matching engine is enhanced: previously it
recursed to row direction, which means if the number of rows in a
frame is large, it could exceed the limit of stack depth. The new
version recurses over matched pattern variables in a row, which is at
most 26 which should be small enough.
Best reagards,
