A quick temporary hack is to use buffer(b'abc') instead. (buffer() is
so incredibly broken that it lets you hash() even if the underlying
object is broken. :-)
The correct solution is to fix the re library to avoid using hash()
directly on the underlying data type altogether; that never had sound
semantics (as proven by the buffer() hack above).
