Hi Thank you for the reply. Why you assume that a local variable va is modified under the hood by a different function? As long as you don't pass reference to it, you are not able to modify its contents for an outer function. That's interresting, as soon as I read that line I was like "what an idiot". But then, I realized that the issue here was actually the misleading gcc/libc/... from my distribution because, well it "works" even though I'm passing the va_list as an argument and not as a reference...

va_arg is acting weird during inner function calls
