Can it be that the file you try to compile contains an error?

I am just starting and I am not acquainted with Lilypond at all but I 
had a look at the source code. The "d" the failed assertion refers to is 
of type "Direction" and must be 1 or -1. No other values are allowed 
when calling the "at()" method.
