2 years ago It seems that the error occurs at line 73 in src/core/class/column.lisp
So apparently the SLOT-BOUNDP function signals an error because the meta-class for MITO.CLASS.COLUMN::COL-TYPE is an instance of the class BUILT-IN-CLASS SYMBOL
The CLHS specifies [1]: The specific behavior depends on instance's metaclass. An error is never signaled if instance has metaclass standard-class. An error is always signaled if instance has metaclass built-in-class. The consequences are undefined if instance has any other metaclass--an error might or might not be signaled in this situation. Note in particular that the behavior for conditions and structures is not specified.
I'm not sure if this helps anyone else, but I'll keep digging to see if I can figure out how to fix it. But since it works flawlessly in SBCL, maybe it is the SLOT-BOUNDP implementation in ABCL that is the problem?
