The variant you qualify
Several ECUs can share one repository. Context is the image you certify.
The build gives the context
ByteAsk Context indexes the functions and calls your compile commands select. The examples below show what was captured for this domain.
- The problem
- Several ECU variants can share one tree. The image is whichever variant the compile commands build
- This recording
- No variant is resolved. The session is a C++ market-data service, not an ECU
The AUTOSAR rule further down is a separate lookup. The session quotes a C++ Core Guidelines line.
How ByteAsk Context worksChecks from a recorded C++ session
A C++ market-data service, not an ECU. Guideline lookup, then those two checks. The AUTOSAR quote below is separate.

AUTOSAR Guidelines for the Use of the C++14 Language in Critical and Safety-Related Systems (AP Release 18-10)
§A18-5-1 required, implementation, automated · p.344
Rule A18-5-1 (required, implementation, automated) Functions malloc, calloc, realloc and free shall not be used. Rationale C-style allocation/deallocation using malloc/calloc/realloc/free functions is not type safe and does not invoke class’s constructors and destructors.
