VR: extend to verify some cstr benchmarks
Tested on SV-COMP21_valid-memsafety category, changed no answers except for newly verified benchmarks.
Depends on VR: use fixed and refactored version #65.
This are the commits from svcomp22 branch right? Don't know how much they are polished, but they have been quite well tested as they were used in SV-COMP 22. Also, I do not know how much @GiraffeReversed will react on any request for changes, so maybe they are good to be merged as they are? (maybe with some cosmetic changes).
Hi :) I don't really know what the requested cosmetic changes are... (but hopefully I am able to perform them after the exam period). Also, I will gladly try to explain how the code works, once I am back from Erasmus.
