I agree, bittage of IDL and Python have to match, I ran into that problem first yesterday. However, for me slither does not load 32 bit python on 32-bit IDL 8.2.3. It does load on IDL 8.3.
Maybe Chris does have a point with the changes in the API. Maybe the changes are such that only some functionality is affected. That would explain why my own DLMs run without chnages across these DLM versions.

Both are running IDL 8.2 and Python 2.7 (Specifically, the Python(x,y) installation). In both cases, attempting to call pyimport() to import any python module crashes IDL. It happens pretty quickly, so i feel like it's something simple, but not sure.
