I don't know about current versions, but the Merlin assembler used to
come with a program that would generate a source code listing for
Applesoft.  Interspersed among the comments are some bugs.  

One curious example:
There's one number that when typed in to Applesoft (as if you were 
starting a line of BASIC) causes the computer to crash.
