vim-patch:8.2.4261: accessing invalid memory in a regular expression
Problem: Accessing invalid memory when a regular expression checks the
Visual area while matching in a string.
Solution: Do not try matching the Visual area in a string.
https://github.com/vim/vim/commit/679d66c2d21dfe03d0f89b9a818b0aaebb4c3b87
Use CheckScriptFailure() instead of v9.CheckScriptFailure().
