Dear logol and swi-prolog maintainers,

This "fix" suggest there may be more breakage, normally the Release Team 
would schedule binNMU's. Can you please elaborate how ABI is normally 
maintained within swi-prolog, such that the rebuilds can be detected and 
requested? I fail to see how in the case of logol and swi-prolog the 
right versions are chosen. In other words, I think the "fixed" logol can 
migrate to testing even if swi-prolog does not and will be broken in 
testing until swi-prolog can migrate. Normally *versioned* dependencies 
should prevent this.

I checked, there are more reverse build dependencies of swi-prolog, I'm 
afraid there's more breakage that hasn't been detected yet. (eye seems 
to go in lockstep, so that package currently seems OK).
