Known Solver Issues

Princess

  • Princess is recursive and might require a large amount of stack memory. If you experience stack overflows or Princess returns OutOfMemory, try increasing the stack size with the JVM parameter -Xss.
  • Requesting termination via the ShutdownNotifier works only in limited circumstances.

SMTInterpol

  • SMTInterpol does not support multiple concurrent stacks under the same context.
  • Variables and UFs that are used for the first time after a solver stack has been created will be deleted on the next call to pop() and will be invalid afterwards. This will change with one of the next SMTInterpol versions (cf. #69).

Z3

  • Z3 interpolation procedure might require a large amount of stack memory. If you get segmentation fault on interpolation, try increasing the stack size with the JVM parameter -Xss.
