Pointer checks and memory bounds

epardo — Thu, 08 Aug 2024 13:16:41 GMT

The former icpc was able to check bounds of dynamically allocated memory and memory related to pointers by using flags like

icpc -check-pointers=rw

That was very useful for debugging programs, specially for early stage programmers in our team. However, with the new compiler versions like icpx this flag does not work. Is there any option to check memory bounds and pointers with icpx?
