Indeed, I've found some such situations. Not so much for running
applications, but rather when building them (where the configure script
looks at "the architecture" and then assume pointers will be 64bit long).
This said, I've been running such "hybrid" systems for the last 15 years
or so and over the years these problems have largely disappeared (there
were also several other problems where the 64bit kernel wouldn't provide
support for some particular operations to 32bit applications).
