   @encthenet I've gotten caught off guard by this: Harfbuzz does not like processing empty data!

   So I adjusted my Haskell language bindings to handle that case specially, so that in normal operation there should be no errors. (I do throw OOM errors as exceptions)

     To any C standard lawyers, someone said:
     assing NULL with a length of 0 to library functions (representing e.g. an empty array) is also Undefined behavior.

     BUT, what if malloc(0) returns NULL (iirc, it can, if not feel free to correct me)? Wouldn't that require the library functions to handle it? Though this is likely a problem where an implementation isn't compliant due to compiler mismatch.
