I have a strange (low level) problem with the Data.Text library.

Thanks for bringing this up.

Running the simple program below on a certain text file causes a low level error.

This only happens on a single file? Can you mail it to me directly, perhaps?

I might be able to reproduce it based on the "Illegal byte sequence" error you are seeing, which makes me think it's not a UTF-8-encoded file, but that low-level crash should of course not happen.

What version of GHC and the text library are you using?
