alt Hacker NewsThat's undefined behavior in C I thought? You're addressing the memory of a stack frame that already collapsed when it returned. I think it's ok for compilers to either segfault or work like you'd think they would for that example in C.
You can pass pointers to earlier frames in the stack, they're still active, but you can't return a pointer to an expired stack frame.
I think you're basically agreeing with the person you're replying to; they're pointing out that Solod doesn't really provide the "safety of Go" since the translation trivially exposes the user to UB that would not be present in Go.
