| 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. | ||||

Branch CR31024_1 has been created by abv. SHA-1: 603b5cf0930f6a0e216b388bcea446d71330f8ca Detailed log of new commits: Author: kgv Date: Thu Oct 3 06:49:59 2019 +0300 0031024: Coding - invalid left shift in BVH_RadixSorter::Perform() using -fsanitize=undefined Standard_Integer has been replaced by unsigned int for bit operations. |

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. |
