Most likely you ran into 3D-syntax (as i did before :)
http://lists.racket-lang.org/dev/archive//2012-July/010101.html

Without knowing the exact location of the error, i think you tried to pass  
a ctype from phase 1 to 0 by simply inserting it there (e.g by #,ctype).  
But as a ctype can't be printed it can't be stored in the compiled  
bytecode.
