To fix the issue, ensure that the multiplication uses the larger type (
size_t) before performing the computation, not only after. This is done by explicitly casting one (or both) of the operands tosize_tbefore multiplying. Change all instances ofs * layersCollapsein the relevant region so their multiplication is performed insize_tarithmetic, ensuring the multiplication cannot overflow a 32-bit integer even if either operand is large. Only the usages shown on lines 698, 699, 700, 712, 715, 718 need review, but CodeQL only flagged line 698; other usages can be safely left, but it would be good practice to fix similar expressions in the region as well.No additional includes, methods, or variable definitions are required, as
size_tand explicit casting are standard in C++.Suggested fixes powered by Copilot Autofix. Review carefully before merging.
