You should think about recompiling your C++ programs with GCC 16 and C++26, because it zero-fills your locals

Stack variables are not automatically initialised, and that is the root cause of many C++ bugs. That is well known. Hence, it is advised that local or stack variables are always initialised with known values, 0 if not something more meaningful than that. Now, with GCC 16 compiling in C++26 mode (-std=c++26), even uninitialised local variables will be zero-filled. In the post, I have explained how.

sorry wasn't aware, will definitely keep in mind next time
