--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- >From Bug 119429 comment 17: If I make the file `ignorelist.txt`: ``` #!special-case-list-v1 [integer] # src:.*gcc.*include.*c\+\+.* ``` And then compile with: ``` clang++ -std=c++23 -fsanitize=integer -fno-sanitize-recover=all -fsanitize-ignorelist=ignorelist.txt example.cc -o example ``` The `UndefinedBehaviorSanitizer` is no longer getting triggered, or being injected into the libstdc++ code for that matter.
