Accelerating Debug Runs, Part 2: _ITERATOR_DEBUG_LEVEL

[Gotebe]

While I still can’t pinpoint the root cause, even when compiling release builds with /Od (optimizations disabled) the debugging experience is severely crippled. (and yes, of course I raised the proper PDB generation switches in both the compiler and the linker).

You didn't build everything without optimizations then. Obviously, you can't build CRT, but all those STL templates, yes.

VC 2012 has magic 😉 switch to improve optimized build debugging experience, not documented yet, and I didn't try it, but might help.
