Without sounding alarmist, I can break my machine using bash. I also have a

You included some C++ code (or possibly C code, if you're allowed to
declare variables after the start of a block now).  But I don't see any
bash commands.  How exactly is bash involved with your code or the bug
you found?

ANSI c99 adopted c++ flexibility with variable declaration. though I still consider it bad practice to rely on it needlessly.
