| Summary | 0031024: Coding - invalid left shift in BVH_RadixSorter::Perform() using -fsanitize=undefined | ||||||||||||
| Description | Running a large of test cases with -fsanitize=undefined I see this error: opencascade-7.4/src/BVH/BVH_RadixSorter.hxx:209:34: runtime error: left shift of 16777301 by 8 places cannot be represented in type 'Standard_Integer' (aka 'int') opencascade-7.4/src/BVH/BVH_RadixSorter.hxx:209:34: runtime error: left shift of 33554432 by 8 places cannot be represented in type 'Standard_Integer' (aka 'int') One solution is to change: Standard_Interger aVoxel to Standard_Size aVoxel | ||||||||||||
| Steps To Reproduce | Compile OCCT with -fsanitize=undefined and run the test suite. | ||||||||||||

I have updated the patch to use unsigned not only in calculation of a bit mask, but also in places where it is further stored and checked. Eugene, can you please have a look at the patch in branch CR31024_1? |

Reviewed, although tests have not been restarted after update. I have restarted the job CR31024-master-KGV with new branch. |
