C++20 is here and has been supported in MSVC since 16.11, but today's post is not about how you can use it, but rather how we used it to effectively eliminate an entire class of runtime bugs by hoisting a check into compile-time. Let's get right into it! Humble beginnings In compiler design one of the very first things you need is a way to convey...

Jim Hogg

Background We have all used the Visual Studio Debugger to step through code, in the hunt for bugs.  For C or C++ code, that Debugger relies upon a file, with the extension ".pdb", called the "Program DataBase", or simply "the PDB".  The PDB is written by the Linker when you build your program; it contains line-number and symbols information. But wh...
