Yes, I had similar problems in past with compound if clauses...

Maybe you're right and fddnm is not up anymore to the whole task, however, I do
not think it is necessary to remove from source tree, if you can prevent the
segmentation fault (probably using try:except statements) and skip such files
printing to console “file x cannot be rendered.”

After all, fddnm have its uses. Specially testing new dialog submissions...
