maybe it's a symbol versioning things. if an incompatible bugfix/change
is introduced, it is possible to just increment the symbol version
so new programs compiled against the library use the newer
version of the function, and older binaries (potentially relying
on the old behaviour) get the old one. try recompiling
1.5.2 and see if it starts behaving the same as 2.0...
