That’s not true.
A conforming implementation may chose to melt your computer - and you can choose to not use that implementation. But clang and gcc will never melt your Linux.
Once again, a real life example where that is relevant is an embedded device with no memory protection. If you overwrite a buffer you can overwrite the OS code - breaking your computer and requiring you to flash the memory.
It seems there is a lot of misguided accusations going around about who misunderstands UB.

- grandempire 2y agoIf you're referring to what might happen when you overwrite a buffer in privileged kernel code, yes - but that is true regardless of clang, gcc, or what the C standard says about UB.
