10.15.12 Known Problems with This Release

• Some Prolog libraries that depend on foreign code (e.g. library(bdb), library(tcltk)) can only be loaded by one SICStus run-time in the same process. The second run-time that attempts to load e.g. library(bdb), will raise an exception. This only affects code that loads several SICStus run-times (e.g. using the Java interface).
• The API for associating destructors with external objects is in place but is not documented. It is, at present, only used by the COM client library. Contact sicstus-support@sics.se if you have any questions about it.
• See 3.9 Incompatibilities.
