We can't say for sure, but it's quite likely. This is another textbook case of #UndefinedBehavior in C++ code. Dereferencing `std::map::end()` causes this, as this iterator points past the last element in a `std::map`.
We know, #undefinedbehavior is out of compilers' scope, but it doesn't mean that the codebase has immunity. Here's a classic UB scenario, triggered only if 'regIdx == 31'. Probably, it seems impossible or very unlikely, so the error has been unnoticed. But who knows what tomorrow will bring?
Today is the perfect day to listen to some #undefinedbehavior #psytrance #music
