| Summary | 0029859: Coding - GCC compiler warning -Warray-bounds in IntPatch_InterferencePolyhedron.cxx | ||||
| Description | OCCT-ARCH463-64-opt-compile IntPatch_InterferencePolyhedron.cxx:905, GNU C Compiler 4 (gcc), Priority: Normal array subscript is above array bounds [-Warray-bounds] This looks as real issue (even if not affecting anything): the cycle copies too many elements of array, so the last copy will be for uninitialized data (but still in the buffer, thus no actual out of bounds error). | ||||
| Steps To Reproduce | Ask INV to build on ARCH463-64 system | ||||
| Tags | No tags attached. | ||||
| Test case number | Not needed | ||||

This issue became critical because Debian80-64 will be based Linux OS on new jenkins-test-12 |
|
|
The warning is reproduced on Debian90-64 + gcc --version gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516 |
