Annotation is valid for all loop-free paths from loop head at line 36 to check that procedure precondition always holds at line 36. Annotation is valid for all loop-free paths from entry of procedure main to loop head at line 36. Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to check that a call to reach_error is unreachable at line 16. Annotation is valid for all loop-free paths from entry of procedure assume_abort_if_not to exit of procedure assume_abort_if_not. Annotation is valid for all loop-free paths from loop head at line 36 to check that procedure precondition always holds at line 37. Annotation is valid for all loop-free paths from entry of procedure __VERIFIER_assert to exit of procedure __VERIFIER_assert. * Results from de.uni_freiburg.informatik.ultimate.core: - StatisticsResult: Toolchain Benchmarks Benchmark results are: * Witness Parser took 0.95ms.
