Interesting Compiler Error

Hello, 

When attempting to compile a file with bigloo 4.3a (beta16Oct16), I am recieving an error I have never seen before. A truncated version of the error message can be found below. The error may not be specific to bigloo 4.3a; I have not tried compiling with an earlier Bigloo version yest. Does any one know what this error indicates? If it helps, I am seeing this error when compiling recette/tabled.scm found at https://github.com/donaldsonjw/bkanren. I recently revisited the project and was attempting to properly merge the changes made by Peter Kourzanov. Any help would be appreciated. 
Thanks,Joseph Donaldson
