Vincent Rabaud 3880d059b3 Merge pull request #24260 from vrabaud:ubsan ... Fix undefined behavior arithmetic in copyMakeBorder and adjustROI. #24260 This is due to the undefined: negative int multiplied by size_t pointer increment. To test, compile with: ``` mkdir build cd build cmake ../ -DCMAKE_C_FLAGS_INIT="-fsanitize=undefined" -DCMAKE_CXX_FLAGS_INIT="-fsanitize=undefined" -DCMAKE_C_COMPILER="/usr/bin/clang" -DCMAKE_CXX_COMPILER="/usr/bin/clang++" -DCMAKE_SHARED_LINKER_FLAGS="-fsanitize=undefined -lubsan" ``` And run: ``` make -j opencv_test_core && ./bin/opencv_test_core --gtest_filter=*UndefinedBehavior* ``` ### Pull Request Readiness Checklist See details at https://github.com/opencv/opencv/wiki/How_to_contribute#making-a-good-pull-request - [x] I agree to contribute to the project under Apache 2 License. - [x] To the best of my knowledge, the proposed patch is not based on a code under GPL or another license that is incompatible with OpenCV - [x] The PR is proposed to the proper branch - [x] There is a reference to the original bug report and related work - [x] There is accuracy test, performance test and test data in opencv_extra repository, if applicable Patch to opencv_extra has the same branch name. - [x] The feature is well documented and sample code can be built with the project CMake		1 year ago
