How can it be this was reported almost two years ago and nothing has been done?
The fact that is hasn't been fixed yet may be a signal that, in practice, this hasn't bitten anyone hard enough to motivate a patch submission. In which case, one could argue that the bugs are being tackled in a somewhat rational order.
It may be instructive to consider why you yourself haven't submitted a fix. Perhaps that reason is common across many of those capable of submitting a fix.
I hacked around in clang for a bit for a compiler project. I think it would have taken me weeks or months to get to the point where I was able to fix the equivalent bug (if it existed) in Clang. Compilers are big, hard to debug projects. And, IMHO, the Clang/LLVM code is much more approachable than GCC. Not all developers are hobbyists that can afford to detour from their work for weeks or months to ramp up on GCC to fix this.
I'd also point out that this is the kind of bug that could exist and be triggering in a lot of code as we speak but no one (besides the author of this blog post) have caught it. I think it's insane to ignore a bug like this.
That's not my take on it. It doesn't read like an urge to fix it yourself, rather it's literally an urge to consider why you haven't, in order to understand why others also have not.
"Not all developers are hobbyists that can afford to detour from their work for weeks or months to ramp up on GCC to fix this" seems like an appropriate response and probably more or less the point that the GP wanted to make.
I totally agree. GCC is reputed to be a complex beast, and few people have the spare time to get to the point where they can make the fix.
To clarify my original point: The bug apparently wasn't bad enough to cause anyone like yourself to either (a) fix it, or (b) pay someone else to fix it. So I'm at peace with this at a kind of meta/process level.
User u{make_1(), make_2()};
process(u);
That's why I don't use RAII. It comes with a massive amount of baggage.
